 # Nostalgia
 
-## Setup
+## Prerequisites
 
-### Linux
+* Install GCC, Clang, or Visual Studio with C++20 support
+* Install [devkitPro](https://devkitpro.org/wiki/Getting_Started) to build for GBA
+    * Install the gba-dev package
+* Install Python 3
+* Install Ninja, Make, and CMake
+* Consider also installing ccache for faster subsequent build times
 
-Make sure conan is using the C++11 version of libstdc++.
+### Debian
 
-	conan profile update settings.compiler.libcxx=libstdc++11 default
-
-### macOS
-
-Install and use gmake instead of the make that comes with the system.
+For Debian (and probably other Linux distros, but the package names will
+probably differ), install the following additional packages:
+* pkg-config
+* xorg-dev
+* libgtk-3-dev
+* python3-mypy
 
 ## Build
 
-Build options: release, debug, gba, gba-debug
+Build options: release, debug, asan, gba, gba-debug
 
-	make purge conan configure-{gba,release,debug} install
+	make purge configure-{gba,release,debug} build
+
+## Run
+
+### Studio
+
+	make run-studio
+
+### Native Platform
+
+	make run
+
+### GBA
+
+	make gba-run
+
+## Contributing
+
+Please read the [Developer Handbook](developer-handbook.md) for information on
+coding standards.

+ *
+ * The types in khrplatform.h should only be used to define API-specific types.

+ *    khronos_uint8_t             unsigned 8  bit

+ *    khronos_stime_nanoseconds_t signed time interval in nanoseconds
+ *    khronos_boolean_enum_t      enumerated boolean type. This should

+
+## Introduction
+
+GLFW is an Open Source, multi-platform library for OpenGL, OpenGL ES and Vulkan
+application development.  It provides a simple, platform-independent API for
+creating windows, contexts and surfaces, reading input, handling events, etc.
+
+GLFW natively supports Windows, macOS and Linux and other Unix-like systems.  On
+Linux both Wayland and X11 are supported.
+
+GLFW is licensed under the [zlib/libpng
+license](https://www.glfw.org/license.html).
+
+You can [download](https://www.glfw.org/download.html) the latest stable release
+as source or Windows binaries.  Each release starting with 3.0 also has
+a corresponding [annotated tag](https://github.com/glfw/glfw/releases) with
+source and binary archives.
+
+The [documentation](https://www.glfw.org/docs/latest/) is available online and is
+included in all source and binary archives.  See the [release
+notes](https://www.glfw.org/docs/latest/news.html) for new features, caveats and
+deprecations in the latest release.  For more details see the [version
+history](https://www.glfw.org/changelog.html).
+
+The `master` branch is the stable integration branch and _should_ always compile
+and run on all supported platforms, although details of newly added features may
+change until they have been included in a release.  New features and many bug
+fixes live in [other branches](https://github.com/glfw/glfw/branches/all) until
+they are stable enough to merge.
+
+If you are new to GLFW, you may find the
+[tutorial](https://www.glfw.org/docs/latest/quick.html) for GLFW 3 useful.  If
+you have used GLFW 2 in the past, there is a [transition
+guide](https://www.glfw.org/docs/latest/moving.html) for moving to the GLFW
+3 API.
+
+GLFW exists because of the contributions of [many people](CONTRIBUTORS.md)
+around the world, whether by reporting bugs, providing community support, adding
+features, reviewing or testing code, debugging, proofreading docs, suggesting
+features or fixing bugs.
+
+
+## Compiling GLFW
+
+GLFW is written primarily in C99, with parts of macOS support being written in
+Objective-C.  GLFW itself requires only the headers and libraries for your OS
+and window system.  It does not need any additional headers for context creation
+APIs (WGL, GLX, EGL, NSGL, OSMesa) or rendering APIs (OpenGL, OpenGL ES, Vulkan)
+to enable support for them.
+
+GLFW supports compilation on Windows with Visual C++ 2013 and later, MinGW and
+MinGW-w64, on macOS with Clang and on Linux and other Unix-like systems with GCC
+and Clang.  It will likely compile in other environments as well, but this is
+not regularly tested.
+
+There are [pre-compiled binaries](https://www.glfw.org/download.html) available
+for all supported compilers on Windows and macOS.
+
+See the [compilation guide](https://www.glfw.org/docs/latest/compile.html) for
+more information about how to compile GLFW yourself.
+
+
+## Using GLFW
+
+See the [documentation](https://www.glfw.org/docs/latest/) for tutorials, guides
+and the API reference.
+
+
+## Contributing to GLFW
+
+See the [contribution
+guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for
+more information.
+
+
+## System requirements
+
+GLFW supports Windows XP and later and macOS 10.8 and later.  Linux and other
+Unix-like systems running the X Window System are supported even without
+a desktop environment or modern extensions, although some features require
+a running window or clipboard manager.  The OSMesa backend requires Mesa 6.3.
+
+See the [compatibility guide](https://www.glfw.org/docs/latest/compat.html)
+in the documentation for more information.
+
+
+## Dependencies
+
+GLFW itself needs only CMake 3.1 or later and the headers and libraries for your
+OS and window system.
+
+The examples and test programs depend on a number of tiny libraries.  These are
+located in the `deps/` directory.
+
+ - [getopt\_port](https://github.com/kimgr/getopt_port/) for examples
+   with command-line options
+ - [TinyCThread](https://github.com/tinycthread/tinycthread) for threaded
+   examples
+ - [glad2](https://github.com/Dav1dde/glad) for loading OpenGL and Vulkan
+   functions
+ - [linmath.h](https://github.com/datenwolf/linmath.h) for linear algebra in
+   examples
+ - [Nuklear](https://github.com/Immediate-Mode-UI/Nuklear) for test and example UI
+ - [stb\_image\_write](https://github.com/nothings/stb) for writing images to disk
+
+The documentation is generated with [Doxygen](https://doxygen.org/) if CMake can
+find that tool.
+
+
+## Reporting bugs
+
+Bugs are reported to our [issue tracker](https://github.com/glfw/glfw/issues).
+Please check the [contribution
+guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for
+information on what to include when reporting a bug.

+* TinyCThread is a minimal, portable implementation of basic threading
+* classes for C.
+*
+* They closely mimic the functionality and naming of the C11 standard, and
+* should be easily replaceable with the corresponding standard variants.
+*
+* @section port_sec Portability
+* The Win32 variant uses the native Win32 API for implementing the thread
+* classes, while for other systems, the POSIX threads API (pthread) is used.
+*
+* @section misc_sec Miscellaneous
+* The following special keywords are available: #_Thread_local.
+*
+* For more detailed information, browse the different sections of this
+* documentation. A good place to start is:
+* tinycthread.h.

+  <description summary="Protocol for requesting fractional surface scales">
+    This protocol allows a compositor to suggest for surfaces to render at
+    fractional scales.
+
+    A client can submit scaled content by utilizing wp_viewport. This is done by
+    creating a wp_viewport object for the surface and setting the destination
+    rectangle to the surface size before the scale factor is applied.
+
+    The buffer size is calculated by multiplying the surface size by the
+    intended scale.
+
+    The wl_surface buffer scale should remain set to 1.
+
+    If a surface has a surface-local size of 100 px by 50 px and wishes to
+    submit buffers with a scale of 1.5, then a buffer of 150px by 75 px should
+    be used and the wp_viewport destination rectangle should be 100 px by 50 px.
+
+    For toplevel surfaces, the size is rounded halfway away from zero. The
+    rounding algorithm for subsurface position and size is not defined.

+  <description summary="protocol for constraining pointer motions">
+    This protocol specifies a set of interfaces used for adding constraints to
+    the motion of a pointer. Possible constraints include confining pointer
+    motions to a given region, or locking it to its current position.
+
+    In order to constrain the pointer, a client must first bind the global
+    interface "wp_pointer_constraints" which, if a compositor supports pointer
+    constraints, is exposed by the registry. Using the bound global object, the
+    client uses the request that corresponds to the type of constraint it wants
+    to make. See wp_pointer_constraints for more details.
+
+    Warning! The protocol described in this file is experimental and backward
+    incompatible changes may be made. Backward compatible changes may be added
+    together with the corresponding interface version bump. Backward
+    incompatible changes are done by bumping the version number in the protocol
+    and interface names and resetting the interface version. Once the protocol
+    is to be declared stable, the 'z' prefix and the version number in the
+    protocol and interface names are removed and the interface version number is
+    reset.

+      The global interface exposing pointer constraining functionality. It
+      exposes two requests: lock_pointer for locking the pointer to its

+
+      The lock_pointer and confine_pointer requests create the objects
+      wp_locked_pointer and wp_confined_pointer respectively, and the client can
+      use these objects to interact with the lock.
+

+	future, when the compositor deems implementation-specific constraints
+	are satisfied, the pointer lock will be activated and the compositor
+	sends a locked event.
+
+	The protocol provides no guarantee that the constraints are ever
+	satisfied, and does not require the compositor to send an error if the
+	constraints cannot ever be satisfied. It is thus possible to request a
+	lock that will never activate.
+
+	There may not be another pointer constraint of any kind requested or

+
+	The intersection of the region passed with this request and the input
+	region of the surface is used to determine where the pointer must be
+	in order for the lock to activate. It is up to the compositor whether to
+	warp the pointer or require some kind of user interaction for the lock
+	to activate. If the region is null the surface input region is used.
+
+	A surface may receive pointer focus without the lock being activated.
+
+	The request creates a new object wp_locked_pointer which is used to
+	interact with the lock as well as receive updates about its state. See
+	the the description of wp_locked_pointer for further information.
+
+	Note that while a pointer is locked, the wl_pointer objects of the
+	corresponding seat will not emit any wl_pointer.motion events, but

+      used as the source, and the surface size is as defined in
+      wl_surface.attach.
+
+      If the destination size is set, it causes the surface size to become
+      dst_width, dst_height. The source (rectangle) is scaled to exactly
+      this size. This overrides whatever the attached wl_buffer size is,
+      unless the wl_buffer is NULL. If the wl_buffer is NULL, the surface
+      has no content and therefore no size. Otherwise, the size is always
+      at least 1x1 in surface local coordinates.
+
+      If the source rectangle is set, it defines what area of the wl_buffer is
+      taken as the source. If the source rectangle is set and the destination
+      size is not set, then src_width and src_height must be integers, and the
+      surface size becomes the source rectangle size. This results in cropping
+      without scaling. If src_width or src_height are not integers and
+      destination size is not set, the bad_size protocol error is raised when
+      the surface state is applied.
+
+      The coordinate transformations from buffer pixel coordinates up to
+      the surface-local coordinates happen in the following order:
+        1. buffer_transform (wl_surface.set_buffer_transform)
+        2. buffer_scale (wl_surface.set_buffer_scale)
+        3. crop and scale (wp_viewport.set*)
+      This means, that the source rectangle coordinates of crop and scale
+      are given in the coordinates after the buffer transform and scale,
+      i.e. in the coordinates that would be the surface-local coordinates
+      if the crop and scale was not applied.
+
+      If src_x or src_y are negative, the bad_value protocol error is raised.
+      Otherwise, if the source rectangle is partially or completely outside of
+      the non-NULL wl_buffer, then the out_of_buffer protocol error is raised
+      when the surface state is applied. A NULL wl_buffer does not raise the
+      out_of_buffer error.
+
+      If the wl_surface associated with the wp_viewport is destroyed,
+      all wp_viewport requests except 'destroy' raise the protocol error
+      no_surface.
+
+      If the wp_viewport object is destroyed, the crop and scale
+      state is removed from the wl_surface. The change will be applied
+      on the next wl_surface.commit.

+  <description summary="Protocol for requesting activation of surfaces">
+    The way for a client to pass focus to another toplevel is as follows.
+
+    The client that intends to activate another toplevel uses the
+    xdg_activation_v1.get_activation_token request to get an activation token.
+    This token is then forwarded to the client, which is supposed to activate
+    one of its surfaces, through a separate band of communication.
+
+    One established way of doing this is through the XDG_ACTIVATION_TOKEN
+    environment variable of a newly launched child process. The child process
+    should unset the environment variable again right after reading it out in
+    order to avoid propagating it to other child processes.
+
+    Another established way exists for Applications implementing the D-Bus
+    interface org.freedesktop.Application, which should get their token under
+    activation-token on their platform_data.
+
+    In general activation tokens may be transferred across clients through
+    means not described in this protocol.
+
+    The client to be activated will then pass the token
+    it received to the xdg_activation_v1.activate request. The compositor can
+    then use this token to decide how to react to the activation request.
+
+    The token the activating client gets may be ineffective either already at
+    the time it receives it, for example if it was not focused, for focus
+    stealing prevention. The activating client will have no way to discover
+    the validity of the token, and may still forward it to the to be activated
+    client.
+
+    The created activation token may optionally get information attached to it
+    that can be used by the compositor to identify the application that we
+    intend to activate. This can for example be used to display a visual hint
+    about what application is being started.
+
+    Warning! The protocol described in this file is currently in the testing
+    phase. Backward compatible changes may be added together with the
+    corresponding interface version bump. Backward incompatible changes can
+    only be done by creating a new major version of the extension.

+## Asking a question
+
+Questions about how to use GLFW should be asked either in the [support
+section](https://discourse.glfw.org/c/support) of the forum, under the [Stack
+Overflow tag](https://stackoverflow.com/questions/tagged/glfw) or [Game
+Development tag](https://gamedev.stackexchange.com/questions/tagged/glfw) on
+Stack Exchange.
+
+Questions about the design or implementation of GLFW or about future plans
+should be asked in the [dev section](https://discourse.glfw.org/c/dev) of the
+forum.  Please don't open a GitHub issue to discuss design questions without
+first checking with a maintainer.
+
+
+## Reporting a bug
+
+If GLFW is behaving unexpectedly at run-time, start by setting an [error
+callback](https://www.glfw.org/docs/latest/intro_guide.html#error_handling).
+GLFW will often tell you the cause of an error via this callback.  If it
+doesn't, that might be a separate bug.
+
+If GLFW is crashing or triggering asserts, make sure that all your object
+handles and other pointers are valid.
+
+For bugs where it makes sense, a short, self contained example is absolutely
+invaluable.  Just put it inline in the body text.  Note that if the bug is
+reproducible with one of the test programs that come with GLFW, just mention
+that instead.
+
+__Don't worry about adding too much information__.  Unimportant information can
+be abbreviated or removed later, but missing information can stall bug fixing,
+especially when your schedule doesn't align with that of the maintainer.
+
+__Please provide text as text, not as images__.  This includes code, error
+messages and any other text.  Text in images cannot be found by other users
+searching for the same problem and may have to be re-typed by maintainers when
+debugging.
+
+You don't need to manually indent your code or other text to quote it with
+GitHub Markdown; just surround it with triple backticks:
+
+    ```
+    Some quoted text.
+    ```
+
+You can also add syntax highlighting by appending the common file extension:
+
+    ```c
+    int five(void)
+    {
+        return 5;
+    }
+    ```
+
+There are issue labels for both platforms and GPU manufacturers, so there is no
+need to mention these in the subject line.  If you do, it will be removed when
+the issue is labeled.
+
+If your bug is already reported, please add any new information you have, or if
+it already has everything, give it a :+1:.
+
+
+### Reporting a compile or link bug
+
+__Note:__ GLFW needs many system APIs to do its job, which on some platforms
+means linking to many system libraries.  If you are using GLFW as a static
+library, that means your application needs to link to these in addition to GLFW.
+
+__Note:__ Check the [Compiling
+GLFW](https://www.glfw.org/docs/latest/compile.html) guide and or [Building
+applications](https://www.glfw.org/docs/latest/build.html) guide for before
+opening an issue of this kind.  Most issues are caused by a missing package or
+linker flag.
+
+Always include the __operating system name and version__ (e.g. `Windows
+7 64-bit` or `Ubuntu 15.10`) and the __compiler name and version__ (e.g. `Visual
+C++ 2015 Update 2`).  If you are using an official release of GLFW,
+include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the
+__GLFW commit ID__ (e.g.  `3795d78b14ef06008889cc422a1fb8d642597751`) from Git.
+
+Please also include the __complete build log__ from your compiler and linker,
+even if it's long.  It can always be shortened later, if necessary.
+
+
+#### Quick template

+
+### Reporting a segfault or other crash bug
+
+Always include the __operating system name and version__ (e.g. `Windows
+7 64-bit` or `Ubuntu 15.10`).  If you are using an official release of GLFW,
+include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the
+__GLFW commit ID__ (e.g.  `3795d78b14ef06008889cc422a1fb8d642597751`) from Git.
+
+Please also include any __error messages__ provided to your application via the
+[error
+callback](https://www.glfw.org/docs/latest/intro_guide.html#error_handling) and
+the __full call stack__ of the crash, or if the crash does not occur in debug
+mode, mention that instead.

+
+
+### Reporting a context creation bug
+
+__Note:__ Windows ships with graphics drivers that do not support OpenGL.  If
+GLFW says that your machine lacks support for OpenGL, it very likely does.
+Install drivers from the computer manufacturer or graphics card manufacturer
+([Nvidia](https://www.geforce.com/drivers),
+[AMD](https://www.amd.com/en/support),
+[Intel](https://www-ssl.intel.com/content/www/us/en/support/detect.html)) to
+fix this.
+
+__Note:__ AMD only supports OpenGL ES on Windows via EGL.  See the
+[GLFW\_CONTEXT\_CREATION\_API](https://www.glfw.org/docs/latest/window_guide.html#window_hints_ctx)
+hint for how to select EGL.
+
+Please verify that context creation also fails with the `glfwinfo` tool before
+reporting it as a bug.  This tool is included in the GLFW source tree as
+`tests/glfwinfo.c` and is built along with the library.  It has switches for all
+GLFW context and framebuffer hints.  Run `glfwinfo -h` for a complete list.
+
+Always include the __operating system name and version__ (e.g. `Windows
+7 64-bit` or `Ubuntu 15.10`).  If you are using an official release of GLFW,
+include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the
+__GLFW commit ID__ (e.g.  `3795d78b14ef06008889cc422a1fb8d642597751`) from Git.
+
+If you are running your program in a virtual machine, please mention this and
+include the __VM name and version__ (e.g. `VirtualBox 5.1`).
+
+Please also include the __GLFW version string__ (`3.2.0 X11 EGL clock_gettime
+/dev/js`), as described
+[here](https://www.glfw.org/docs/latest/intro.html#intro_version_string), the
+__GPU model and driver version__ (e.g. `GeForce GTX660 with 352.79`), and the
+__output of `glfwinfo`__ (with switches matching any hints you set in your
+code) when reporting this kind of bug.  If this tool doesn't run on the machine,
+mention that instead.
+
+
+#### Quick template

+
+
+### Reporting a monitor or video mode bug
+
+__Note:__ On headless systems on some platforms, no monitors are reported.  This
+causes glfwGetPrimaryMonitor to return `NULL`, which not all applications are
+prepared for.
+
+__Note:__ Some third-party tools report more video modes than are approved of
+by the OS.  For safety and compatibility, GLFW only reports video modes the OS
+wants programs to use.  This is not a bug.
+
+The `monitors` tool is included in the GLFW source tree as `tests/monitors.c`
+and is built along with the library.  It lists all information GLFW provides
+about monitors it detects.
+
+Always include the __operating system name and version__ (e.g. `Windows
+7 64-bit` or `Ubuntu 15.10`).  If you are using an official release of GLFW,
+include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the
+__GLFW commit ID__ (e.g.  `3795d78b14ef06008889cc422a1fb8d642597751`) from Git.
+
+If you are running your program in a virtual machine, please mention this and
+include the __VM name and version__ (e.g. `VirtualBox 5.1`).
+
+Please also include any __error messages__ provided to your application via the
+[error
+callback](https://www.glfw.org/docs/latest/intro_guide.html#error_handling) and
+the __output of `monitors`__ when reporting this kind of bug.  If this tool
+doesn't run on the machine, mention this instead.
+
+
+#### Quick template
+
+```
+OS and version:
+Release or commit:
+Error messages:
+monitors output:

+
+
+### Reporting a window, input or event bug
+
+__Note:__ The exact ordering of related window events will sometimes differ.
+
+__Note:__ Window moving and resizing (by the user) will block the main thread on
+some platforms.  This is not a bug.  Set a [refresh
+callback](https://www.glfw.org/docs/latest/window.html#window_refresh) if you
+want to keep the window contents updated during a move or size operation.
+
+The `events` tool is included in the GLFW source tree as `tests/events.c` and is
+built along with the library.  It prints all information provided to every
+callback supported by GLFW as events occur.  Each event is listed with the time
+and a unique number to make discussions about event logs easier.  The tool has
+command-line options for creating multiple windows and full screen windows.
+
+Always include the __operating system name and version__ (e.g. `Windows
+7 64-bit` or `Ubuntu 15.10`).  If you are using an official release of GLFW,
+include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the
+__GLFW commit ID__ (e.g.  `3795d78b14ef06008889cc422a1fb8d642597751`) from Git.
+
+If you are running your program in a virtual machine, please mention this and
+include the __VM name and version__ (e.g. `VirtualBox 5.1`).
+
+Please also include any __error messages__ provided to your application via the
+[error
+callback](https://www.glfw.org/docs/latest/intro_guide.html#error_handling) and
+if relevant, the __output of `events`__ when reporting this kind of bug.  If
+this tool doesn't run on the machine, mention this instead.
+
+__X11:__ If possible, please include what desktop environment (e.g. GNOME,
+Unity, KDE) and/or window manager (e.g. Openbox, dwm, Window Maker) you are
+running.  If the bug is related to keyboard input, please include any input
+method (e.g. ibus, SCIM) you are using.

+### Reporting a documentation bug
+
+If you found a bug in the documentation, including this file, then it's fine to
+just link to that web page or mention that source file.  You don't need to match
+the source to the output or vice versa.
+
+
+### Reporting a website bug
+
+If the bug is in the documentation (anything under `/docs/`) then please see the
+section above.  Bugs in the rest of the site are reported to the [website
+source repository](https://github.com/glfw/website/issues).
+
+
+## Requesting a feature
+
+Please explain why you need the feature and how you intend to use it.  If you
+have a specific API design in mind, please add that as well.  If you have or are
+planning to write code for the feature, see the section below.
+
+If there already is a request for the feature you need, add your specific use
+case unless it is already mentioned.  If it is, give it a :+1:.
+
+
+## Contributing a bug fix
+
+__Note:__ You must have all necessary [intellectual
+property rights](https://en.wikipedia.org/wiki/Intellectual_property) to any
+code you contribute.  If you did not write the code yourself, you must explain
+where it came from and under what license you received it.  Even code using the
+same license as GLFW may not be copied without attribution.
+
+__There is no preferred patch size__.  A one character fix is just as welcome as
+a thousand line one, if that is the appropriate size for the fix.
+
+In addition to the code, a complete bug fix includes:
+
+- Change log entry in `README.md`, describing the incorrect behavior
+- Credits entries in `CONTRIBUTORS.md` for all authors of the bug fix
+
+Bug fixes will not be rejected because they don't include all the above parts,
+but please keep in mind that maintainer time is finite and that there are many
+other bugs and features to work on.
+
+If the patch fixes a bug introduced after the last release, it should not get
+a change log entry.
+
+If you haven't already, read the excellent article [How to Write a Git Commit
+Message](https://chris.beams.io/posts/git-commit/).

+__Note:__ You must have all necessary rights to any code you contribute.  If you
+did not write the code yourself, you must explain where it came from and under
+what license.  Even code using the same license as GLFW may not be copied
+without attribution.
+
+__Note:__ If you haven't already implemented the feature, check first if there
+already is an open issue for it and if it's already being developed in an
+[experimental branch](https://github.com/glfw/glfw/branches/all).
+
+__There is no preferred patch size__.  A one-character change is just as welcome
+as one adding a thousand lines, if that is the appropriate size for the
+feature.
+
+In addition to the code, a complete feature includes:
+
+- Change log entry in `README.md`, listing all new symbols
+- News page entry in `docs/news.md`, briefly describing the feature
+- Guide documentation, with minimal examples, in the relevant guide in the `docs` folder
+- Reference documentation, with all applicable tags
+- Cross-references and mentions in appropriate places
+- Credits entries in `CONTRIBUTORS.md` for all authors of the feature
+
+If the feature requires platform-specific code, at minimum stubs must be added
+for the new platform function to all supported and experimental platforms.
+
+If it adds a new callback, support for it must be added to `tests/event.c`.
+
+If it adds a new monitor property, support for it must be added to
+`tests/monitor.c`.
+
+If it adds a new OpenGL, OpenGL ES or Vulkan option or extension, support
+for it must be added to `tests/glfwinfo.c` and the behavior of the library when
+the extension is missing documented in `docs/compat.md`.
+
+If you haven't already, read the excellent article [How to Write a Git Commit
+Message](https://chris.beams.io/posts/git-commit/).
+
+Features will not be rejected because they don't include all the above parts,
+but please keep in mind that maintainer time is finite and that there are many
+other features and bugs to work on.
+
+Please also keep in mind that any part of the public API that has been included
+in a release cannot be changed until the next _major_ version.  Features can be
+added and existing parts can sometimes be overloaded (in the general sense of
+doing more things, not in the C++ sense), but code written to the API of one
+minor release should both compile and run on subsequent minor releases.

+# Building applications {#build_guide}
+
+[TOC]
+
+This is about compiling and linking applications that use GLFW.  For information on
+how to write such applications, start with the
+[introductory tutorial](@ref quick_guide).  For information on how to compile
+the GLFW library itself, see @ref compile_guide.
+
+This is not a tutorial on compilation or linking.  It assumes basic
+understanding of how to compile and link a C program as well as how to use the
+specific compiler of your chosen development environment.  The compilation
+and linking process should be explained in your C programming material and in
+the documentation for your development environment.
+
+
+## Including the GLFW header file {#build_include}
+
+You should include the GLFW header in the source files where you use OpenGL or
+GLFW.
+
+```c
+#include <GLFW/glfw3.h>
+```
+
+This header defines all the constants and declares all the types and function
+prototypes of the GLFW API.  By default, it also includes the OpenGL header from
+your development environment.  See [option macros](@ref build_macros) below for
+how to select OpenGL ES headers and more.
+
+The GLFW header also defines any platform-specific macros needed by your OpenGL
+header, so that it can be included without needing any window system headers.
+
+It does this only when needed, so if window system headers are included, the
+GLFW header does not try to redefine those symbols.  The reverse is not true,
+i.e. `windows.h` cannot cope if any Win32 symbols have already been defined.
+
+In other words:
+
+ - Use the GLFW header to include OpenGL or OpenGL ES headers portably
+ - Do not include window system headers unless you will use those APIs directly
+ - If you do need such headers, include them before the GLFW header
+
+If you are using an OpenGL extension loading library such as [glad][], the
+extension loader header should be included before the GLFW one.  GLFW attempts
+to detect any OpenGL or OpenGL ES header or extension loader header included
+before it and will then disable the inclusion of the default OpenGL header.
+Most extension loaders also define macros that disable similar headers below it.
+
+[glad]: https://github.com/Dav1dde/glad
+
+```c
+#include <glad/gl.h>
+#include <GLFW/glfw3.h>
+```
+
+Both of these mechanisms depend on the extension loader header defining a known
+macro.  If yours doesn't or you don't know which one your users will pick, the
+@ref GLFW_INCLUDE_NONE macro will explicitly prevent the GLFW header from
+including the OpenGL header.  This will also allow you to include the two
+headers in any order.
+
+```c
+#define GLFW_INCLUDE_NONE
+#include <GLFW/glfw3.h>
+#include <glad/gl.h>
+```
+
+
+### GLFW header option macros {#build_macros}
+
+These macros may be defined before the inclusion of the GLFW header and affect
+its behavior.
+
+@anchor GLFW_DLL
+__GLFW_DLL__ is required on Windows when using the GLFW DLL, to tell the
+compiler that the GLFW functions are defined in a DLL.
+
+The following macros control which OpenGL or OpenGL ES API header is included.
+Only one of these may be defined at a time.
+
+@note GLFW does not provide any of the API headers mentioned below.  They are
+provided by your development environment or your OpenGL, OpenGL ES or Vulkan
+SDK, and most of them can be downloaded from the [Khronos Registry][registry].
+
+[registry]: https://www.khronos.org/registry/
+
+@anchor GLFW_INCLUDE_GLCOREARB
+__GLFW_INCLUDE_GLCOREARB__ makes the GLFW header include the modern
+`GL/glcorearb.h` header (`OpenGL/gl3.h` on macOS) instead of the regular OpenGL
+header.
+
+@anchor GLFW_INCLUDE_ES1
+__GLFW_INCLUDE_ES1__ makes the GLFW header include the OpenGL ES 1.x `GLES/gl.h`
+header instead of the regular OpenGL header.
+
+@anchor GLFW_INCLUDE_ES2
+__GLFW_INCLUDE_ES2__ makes the GLFW header include the OpenGL ES 2.0
+`GLES2/gl2.h` header instead of the regular OpenGL header.
+
+@anchor GLFW_INCLUDE_ES3
+__GLFW_INCLUDE_ES3__ makes the GLFW header include the OpenGL ES 3.0
+`GLES3/gl3.h` header instead of the regular OpenGL header.
+
+@anchor GLFW_INCLUDE_ES31
+__GLFW_INCLUDE_ES31__ makes the GLFW header include the OpenGL ES 3.1
+`GLES3/gl31.h` header instead of the regular OpenGL header.
+
+@anchor GLFW_INCLUDE_ES32
+__GLFW_INCLUDE_ES32__ makes the GLFW header include the OpenGL ES 3.2
+`GLES3/gl32.h` header instead of the regular OpenGL header.
+
+@anchor GLFW_INCLUDE_NONE
+__GLFW_INCLUDE_NONE__ makes the GLFW header not include any OpenGL or OpenGL ES
+API header.  This is useful in combination with an extension loading library.
+
+If none of the above inclusion macros are defined, the standard OpenGL `GL/gl.h`
+header (`OpenGL/gl.h` on macOS) is included, unless GLFW detects the inclusion
+guards of any OpenGL, OpenGL ES or extension loader header it knows about.
+
+The following macros control the inclusion of additional API headers.  Any
+number of these may be defined simultaneously, and/or together with one of the
+above macros.
+
+@anchor GLFW_INCLUDE_VULKAN
+__GLFW_INCLUDE_VULKAN__ makes the GLFW header include the Vulkan
+`vulkan/vulkan.h` header in addition to any selected OpenGL or OpenGL ES header.
+
+@anchor GLFW_INCLUDE_GLEXT
+__GLFW_INCLUDE_GLEXT__ makes the GLFW header include the appropriate extension
+header for the OpenGL or OpenGL ES header selected above after and in addition
+to that header.
+
+@anchor GLFW_INCLUDE_GLU
+__GLFW_INCLUDE_GLU__ makes the header include the GLU header in addition to the
+header selected above.  This should only be used with the standard OpenGL header
+and only for compatibility with legacy code.  GLU has been deprecated and should
+not be used in new code.
+
+@note None of these macros may be defined during the compilation of GLFW itself.
+If your build includes GLFW and you define any these in your build files, make
+sure they are not applied to the GLFW sources.
+
+
+## Link with the right libraries {#build_link}
+
+GLFW is essentially a wrapper of various platform-specific APIs and therefore
+needs to link against many different system libraries.  If you are using GLFW as
+a shared library / dynamic library / DLL then it takes care of these links.
+However, if you are using GLFW as a static library then your executable will
+need to link against these libraries.
+
+On Windows and macOS, the list of system libraries is static and can be
+hard-coded into your build environment.  See the section for your development
+environment below.  On Linux and other Unix-like operating systems, the list
+varies but can be retrieved in various ways as described below.
+
+A good general introduction to linking is [Beginner's Guide to
+Linkers][linker_guide] by David Drysdale.
+
+[linker_guide]: https://www.lurklurk.org/linkers/linkers.html
+
+
+### With Visual C++ and GLFW binaries {#build_link_win32}
+
+If you are using a downloaded [binary
+archive](https://www.glfw.org/download.html), first make sure you have the
+archive matching the architecture you are building for (32-bit or 64-bit), or
+you will get link errors.  Also make sure you are using the binaries for your
+version of Visual C++ or you may get other link errors.
+
+There are two version of the static GLFW library in the binary archive, because
+it needs to use the same base run-time library variant as the rest of your
+executable.
+
+One is named `glfw3.lib` and is for projects with the _Runtime Library_ project
+option set to _Multi-threaded DLL_ or _Multi-threaded Debug DLL_.  The other is
+named `glfw3_mt.lib` and is for projects with _Runtime Library_ set to
+_Multi-threaded_ or _Multi-threaded Debug_.  To use the static GLFW library you
+will need to add `path/to/glfw3.lib` or `path/to/glfw3_mt.lib` to the
+_Additional Dependencies_ project option.
+
+If you compiled a GLFW static library yourself then there will only be one,
+named `glfw3.lib`, and you have to make sure the run-time library variant
+matches.
+
+The DLL version of the GLFW library is named `glfw3.dll`, but you will be
+linking against the `glfw3dll.lib` link library.  To use the DLL you will need
+to add `path/to/glfw3dll.lib` to the _Additional Dependencies_ project option.
+All of its dependencies are already listed there by default, but when building
+with the DLL version of GLFW, you also need to define the @ref GLFW_DLL.  This
+can be done either in the _Preprocessor Definitions_ project option or by
+defining it in your source code before including the GLFW header.
+
+```c
+#define GLFW_DLL
+#include <GLFW/glfw3.h>
+```
+
+All link-time dependencies for GLFW are already listed in the _Additional
+Dependencies_ option by default.
+
+
+### With MinGW-w64 and GLFW binaries {#build_link_mingw}
+
+This is intended for building a program from the command-line or by writing
+a makefile, on Windows with [MinGW-w64][] and GLFW binaries.  These can be from
+a downloaded and extracted [binary archive](https://www.glfw.org/download.html)
+or by compiling GLFW yourself.  The paths below assume a binary archive is used.
+
+If you are using a downloaded binary archive, first make sure you have the
+archive matching the architecture you are building for (32-bit or 64-bit) or you
+will get link errors.
+
+Note that the order of source files and libraries matter for GCC.  Dependencies
+must be listed after the files that depend on them.  Any source files that
+depend on GLFW must be listed before the GLFW library.  GLFW in turn depends on
+`gdi32` and must be listed before it.
+
+[MinGW-w64]: https://www.mingw-w64.org/
+
+If you are using the static version of the GLFW library, which is named
+`libglfw3.a`, do:
+
+```sh
+gcc -o myprog myprog.c -I path/to/glfw/include path/to/glfw/lib-mingw-w64/libglfw3.a -lgdi32
+```
+
+If you are using the DLL version of the GLFW library, which is named
+`glfw3.dll`, you will need to use the `libglfw3dll.a` link library.
+
+```sh
+gcc -o myprog myprog.c -I path/to/glfw/include path/to/glfw/lib-mingw-w64/libglfw3dll.a -lgdi32
+```
+
+The resulting executable will need to find `glfw3.dll` to run, typically by
+keeping both files in the same directory.
+
+When you are building with the DLL version of GLFW, you will also need to define
+the @ref GLFW_DLL macro.  This can be done in your source files, as long as it
+done before including the GLFW header:
+
+```c
+#define GLFW_DLL
+#include <GLFW/glfw3.h>
+```
+
+It can also be done on the command-line:
+
+```sh
+gcc -o myprog myprog.c -D GLFW_DLL -I path/to/glfw/include path/to/glfw/lib-mingw-w64/libglfw3dll.a -lgdi32
+```
+
+
+### With CMake and GLFW source {#build_link_cmake_source}
+
+This section is about using CMake to compile and link GLFW along with your
+application.  If you want to use an installed binary instead, see @ref
+build_link_cmake_package.
+
+With a few changes to your `CMakeLists.txt` you can have the GLFW source tree
+built along with your application.
+
+Add the root directory of the GLFW source tree to your project.  This will add
+the `glfw` target to your project.
+
+```cmake
+add_subdirectory(path/to/glfw)
+```
+
+Once GLFW has been added, link your application against the `glfw` target.
+This adds the GLFW library and its link-time dependencies as it is currently
+configured, the include directory for the GLFW header and, when applicable, the
+@ref GLFW_DLL macro.
+
+```cmake
+target_link_libraries(myapp glfw)
+```
+
+Note that the `glfw` target does not depend on OpenGL, as GLFW loads any OpenGL,
+OpenGL ES or Vulkan libraries it needs at runtime.  If your application calls
+OpenGL directly, instead of using a modern
+[extension loader library](@ref context_glext_auto), use the OpenGL CMake
+package.
+
+```cmake
+find_package(OpenGL REQUIRED)
+```
+
+If OpenGL is found, the `OpenGL::GL` target is added to your project, containing
+library and include directory paths.  Link against this like any other library.
+
+```cmake
+target_link_libraries(myapp OpenGL::GL)
+```
+
+For a minimal example of a program and GLFW sources built with CMake, see the
+[GLFW CMake Starter][cmake_starter] on GitHub.
+
+[cmake_starter]: https://github.com/juliettef/GLFW-CMake-starter
+
+
+### With CMake and installed GLFW binaries {#build_link_cmake_package}
+
+This section is about using CMake to link GLFW after it has been built and
+installed.  If you want to build it along with your application instead, see
+@ref build_link_cmake_source.
+
+With a few changes to your `CMakeLists.txt` you can locate the package and
+target files generated when GLFW is installed.
+
+```cmake
+find_package(glfw3 3.4 REQUIRED)
+```
+
+Once GLFW has been added to the project, link against it with the `glfw` target.
+This adds the GLFW library and its link-time dependencies, the include directory
+for the GLFW header and, when applicable, the @ref GLFW_DLL macro.
+
+```cmake
+target_link_libraries(myapp glfw)
+```
+
+Note that the `glfw` target does not depend on OpenGL, as GLFW loads any OpenGL,
+OpenGL ES or Vulkan libraries it needs at runtime.  If your application calls
+OpenGL directly, instead of using a modern
+[extension loader library](@ref context_glext_auto), use the OpenGL CMake
+package.
+
+```cmake
+find_package(OpenGL REQUIRED)
+```
+
+If OpenGL is found, the `OpenGL::GL` target is added to your project, containing
+library and include directory paths.  Link against this like any other library.
+
+```cmake
+target_link_libraries(myapp OpenGL::GL)
+```
+
+
+### With pkg-config and GLFW binaries on Unix {#build_link_pkgconfig}
+
+This is intended for building a program from the command-line or by writing
+a makefile, on macOS or any Unix-like system like Linux, FreeBSD and Cygwin.
+
+GLFW supports [pkg-config][], and the `glfw3.pc` pkg-config file is generated
+when the GLFW library is built and is installed along with it.  A pkg-config
+file describes all necessary compile-time and link-time flags and dependencies
+needed to use a library.  When they are updated or if they differ between
+systems, you will get the correct ones automatically.
+
+[pkg-config]: https://www.freedesktop.org/wiki/Software/pkg-config/
+
+A typical compile and link command-line when using the static version of the
+GLFW library may look like this:
+
+```sh
+cc $(pkg-config --cflags glfw3) -o myprog myprog.c $(pkg-config --static --libs glfw3)
+```
+
+If you are using the shared version of the GLFW library, omit the `--static`
+flag.
+
+```sh
+cc $(pkg-config --cflags glfw3) -o myprog myprog.c $(pkg-config --libs glfw3)
+```
+
+You can also use the `glfw3.pc` file without installing it first, by using the
+`PKG_CONFIG_PATH` environment variable.
+
+```sh
+env PKG_CONFIG_PATH=path/to/glfw/src cc $(pkg-config --cflags glfw3) -o myprog myprog.c $(pkg-config --libs glfw3)
+```
+
+The dependencies do not include OpenGL, as GLFW loads any OpenGL, OpenGL ES or
+Vulkan libraries it needs at runtime.  If your application calls OpenGL
+directly, instead of using a modern
+[extension loader library](@ref context_glext_auto), you should add the `gl`
+pkg-config package.
+
+```sh
+cc $(pkg-config --cflags glfw3 gl) -o myprog myprog.c $(pkg-config --libs glfw3 gl)
+```
+
+
+### With Xcode on macOS {#build_link_xcode}
+
+If you are using the dynamic library version of GLFW, add it to the project
+dependencies.
+
+If you are using the static library version of GLFW, add it and the Cocoa,
+OpenGL and IOKit frameworks to the project as dependencies.  They can all be
+found in `/System/Library/Frameworks`.
+
+
+### With command-line or makefile on macOS {#build_link_osx}
+
+It is recommended that you use [pkg-config](@ref build_link_pkgconfig) when
+using installed GLFW binaries from the command line on macOS.  That way you will
+get any new dependencies added automatically.  If you still wish to build
+manually, you need to add the required frameworks and libraries to your
+command-line yourself using the `-l` and `-framework` switches.
+
+If you are using the dynamic GLFW library, which is named `libglfw.3.dylib`, do:
+
+```sh
+cc -o myprog myprog.c -lglfw -framework Cocoa -framework OpenGL -framework IOKit
+```
+
+If you are using the static library, named `libglfw3.a`, substitute `-lglfw3`
+for `-lglfw`.
+
+Note that you do not add the `.framework` extension to a framework when linking
+against it from the command-line.
+
+@note Your machine may have `libGL.*.dylib` style OpenGL library, but that is
+for the X Window System and will not work with the macOS native version of GLFW.

+# Standards conformance {#compat_guide}
+
+[TOC]
+
+This guide describes the various API extensions used by this version of GLFW.
+It lists what are essentially implementation details, but which are nonetheless
+vital knowledge for developers intending to deploy their applications on a wide
+range of machines.
+
+The information in this guide is not a part of GLFW API, but merely
+preconditions for some parts of the library to function on a given machine.  Any
+part of this information may change in future versions of GLFW and that will not
+be considered a breaking API change.
+
+
+## X11 extensions, protocols and IPC standards {#compat_x11}
+
+As GLFW uses Xlib directly, without any intervening toolkit library, it has sole
+responsibility for interacting well with the many and varied window managers in
+use on Unix-like systems.  In order for applications and window managers to work
+well together, a number of standards and conventions have been developed that
+regulate behavior outside the scope of the X11 API; most importantly the
+[Inter-Client Communication Conventions Manual][ICCCM] (ICCCM) and [Extended
+Window Manager Hints][EWMH] (EWMH) standards.
+
+[ICCCM]: https://www.tronche.com/gui/x/icccm/
+[EWMH]: https://standards.freedesktop.org/wm-spec/wm-spec-latest.html
+
+GLFW uses the `_MOTIF_WM_HINTS` window property to support borderless windows.
+If the running window manager does not support this property, the
+`GLFW_DECORATED` hint will have no effect.
+
+GLFW uses the ICCCM `WM_DELETE_WINDOW` protocol to intercept the user
+attempting to close the GLFW window.  If the running window manager does not
+support this protocol, the close callback will never be called.
+
+GLFW uses the EWMH `_NET_WM_PING` protocol, allowing the window manager notify
+the user when the application has stopped responding, i.e. when it has ceased to
+process events.  If the running window manager does not support this protocol,
+the user will not be notified if the application locks up.
+
+GLFW uses the EWMH `_NET_WM_STATE_FULLSCREEN` window state to tell the window
+manager to make the GLFW window full screen.  If the running window manager does
+not support this state, full screen windows may not work properly.  GLFW has
+a fallback code path in case this state is unavailable, but every window manager
+behaves slightly differently in this regard.
+
+GLFW uses the EWMH `_NET_WM_BYPASS_COMPOSITOR` window property to tell a
+compositing window manager to un-redirect full screen GLFW windows.  If the
+running window manager uses compositing but does not support this property then
+additional copying may be performed for each buffer swap of full screen windows.
+
+GLFW uses the [clipboard manager protocol][ClipboardManager] to push a clipboard
+string (i.e. selection) owned by a GLFW window about to be destroyed to the
+clipboard manager.  If there is no running clipboard manager, the clipboard
+string will be unavailable once the window has been destroyed.
+
+[clipboardManager]: https://www.freedesktop.org/wiki/ClipboardManager/
+
+GLFW uses the [X drag-and-drop protocol][XDND] to provide file drop events.  If
+the application originating the drag does not support this protocol, drag and
+drop will not work.
+
+[XDND]: https://www.freedesktop.org/wiki/Specifications/XDND/
+
+GLFW uses the XRandR 1.3 extension to provide multi-monitor support.  If the
+running X server does not support this version of this extension, multi-monitor
+support will not function and only a single, desktop-spanning monitor will be
+reported.
+
+GLFW uses the XRandR 1.3 and Xf86vidmode extensions to provide gamma ramp
+support.  If the running X server does not support either or both of these
+extensions, gamma ramp support will not function.
+
+GLFW uses the Xkb extension and detectable auto-repeat to provide keyboard
+input.  If the running X server does not support this extension, a non-Xkb
+fallback path is used.
+
+GLFW uses the XInput2 extension to provide raw, non-accelerated mouse motion
+when the cursor is disabled.  If the running X server does not support this
+extension, regular accelerated mouse motion will be used.
+
+GLFW uses both the XRender extension and the compositing manager to support
+transparent window framebuffers.  If the running X server does not support this
+extension or there is no running compositing manager, the
+`GLFW_TRANSPARENT_FRAMEBUFFER` framebuffer hint will have no effect.
+
+GLFW uses both the Xcursor extension and the freedesktop cursor conventions to
+provide an expanded set of standard cursor shapes.  If the running X server does
+not support this extension or the current cursor theme does not support the
+conventions, the `GLFW_RESIZE_NWSE_CURSOR`, `GLFW_RESIZE_NESW_CURSOR` and
+`GLFW_NOT_ALLOWED_CURSOR` shapes will not be available and other shapes may use
+legacy images.
+
+
+## Wayland protocols and IPC standards {#compat_wayland}
+
+As GLFW uses libwayland directly, without any intervening toolkit library, it
+has sole responsibility for interacting well with every compositor in use on
+Unix-like systems.  Most of the features are provided by the core protocol,
+while cursor support is provided by the libwayland-cursor helper library, EGL
+integration by libwayland-egl, and keyboard handling by
+[libxkbcommon](https://xkbcommon.org/).  In addition, GLFW uses some additional
+Wayland protocols to implement certain features if the compositor supports them.
+
+GLFW uses xkbcommon 0.5.0 to provide key and text input support.  Earlier
+versions are not supported.
+
+GLFW uses the [xdg-shell][] protocol to provide better window management.  This
+protocol is mandatory for GLFW to display a window.
+
+[xdg-shell]: https://wayland.app/protocols/xdg-shell
+
+GLFW uses the [relative-pointer-unstable-v1][] protocol alongside the
+[pointer-constraints-unstable-v1][] protocol to implement disabled cursor.  If
+the running compositor does not support both of these protocols, disabling the
+cursor will have no effect.
+
+[relative-pointer-unstable-v1]: https://wayland.app/protocols/relative-pointer-unstable-v1
+[pointer-constraints-unstable-v1]: https://wayland.app/protocols/pointer-constraints-unstable-v1
+
+GLFW uses the [idle-inhibit-unstable-v1][] protocol to prohibit the screensaver
+from starting.  If the running compositor does not support this protocol, the
+screensaver may start even for full screen windows.
+
+[idle-inhibit-unstable-v1]: https://wayland.app/protocols/idle-inhibit-unstable-v1
+
+GLFW uses the [libdecor][] library for window decorations, where available.
+This in turn provides good quality client-side decorations (drawn by the
+application) on desktop systems that do not support server-side decorations
+(drawn by the window manager).  On systems that do not provide either libdecor
+or xdg-decoration, very basic window decorations are provided.  These do not
+include the window title or any caption buttons.
+
+[libdecor]: https://gitlab.freedesktop.org/libdecor/libdecor
+
+GLFW uses the [xdg-decoration-unstable-v1][] protocol to request decorations to
+be drawn around its windows.  This protocol is part of wayland-protocols 1.15,
+and mandatory at build time.  If the running compositor does not support this
+protocol, a very simple frame will be drawn by GLFW itself, using the
+[viewporter][] protocol alongside subsurfaces.  If the running compositor does
+not support these protocols either, no decorations will be drawn around windows.
+
+[xdg-decoration-unstable-v1]: https://wayland.app/protocols/xdg-decoration-unstable-v1
+[viewporter]: https://wayland.app/protocols/viewporter
+
+GLFW uses the [xdg-activation-v1][] protocol to implement window focus and
+attention requests.  If the running compositor does not support this protocol,
+window focus and attention requests do nothing.
+
+[xdg-activation-v1]: https://wayland.app/protocols/xdg-activation-v1
+
+GLFW uses the [fractional-scale-v1][] protocol to implement fine-grained
+framebuffer scaling.  If the running compositor does not support this protocol,
+the @ref GLFW_SCALE_FRAMEBUFFER window hint will only be able to scale the
+framebuffer by integer scales.  This will typically be the smallest integer not
+less than the actual scale.
+
+[fractional-scale-v1]: https://wayland.app/protocols/fractional-scale-v1
+
+
+## GLX extensions {#compat_glx}
+
+The GLX API is the default API used to create OpenGL contexts on Unix-like
+systems using the X Window System.
+
+GLFW uses the GLX 1.3 `GLXFBConfig` functions to enumerate and select framebuffer pixel
+formats.  If GLX 1.3 is not supported, @ref glfwInit will fail.
+
+GLFW uses the `GLX_MESA_swap_control,` `GLX_EXT_swap_control` and
+`GLX_SGI_swap_control` extensions to provide vertical retrace synchronization
+(or _vsync_), in that order of preference.  When none of these extensions are
+available, calling @ref glfwSwapInterval will have no effect.
+
+GLFW uses the `GLX_ARB_multisample` extension to create contexts with
+multisampling anti-aliasing.  Where this extension is unavailable, the
+`GLFW_SAMPLES` hint will have no effect.
+
+GLFW uses the `GLX_ARB_create_context` extension when available, even when
+creating OpenGL contexts of version 2.1 and below.  Where this extension is
+unavailable, the `GLFW_CONTEXT_VERSION_MAJOR` and `GLFW_CONTEXT_VERSION_MINOR`
+hints will only be partially supported, the `GLFW_CONTEXT_DEBUG` hint will have
+no effect, and setting the `GLFW_OPENGL_PROFILE` or `GLFW_OPENGL_FORWARD_COMPAT`
+hints to `GLFW_TRUE` will cause @ref glfwCreateWindow to fail.
+
+GLFW uses the `GLX_ARB_create_context_profile` extension to provide support for
+context profiles.  Where this extension is unavailable, setting the
+`GLFW_OPENGL_PROFILE` hint to anything but `GLFW_OPENGL_ANY_PROFILE`, or setting
+`GLFW_CLIENT_API` to anything but `GLFW_OPENGL_API` or `GLFW_NO_API` will cause
+@ref glfwCreateWindow to fail.
+
+GLFW uses the `GLX_ARB_context_flush_control` extension to provide control over
+whether a context is flushed when it is released (made non-current).  Where this
+extension is unavailable, the `GLFW_CONTEXT_RELEASE_BEHAVIOR` hint will have no
+effect and the context will always be flushed when released.
+
+GLFW uses the `GLX_ARB_framebuffer_sRGB` and `GLX_EXT_framebuffer_sRGB`
+extensions to provide support for sRGB framebuffers.  Where both of these
+extensions are unavailable, the `GLFW_SRGB_CAPABLE` hint will have no effect.
+
+
+## WGL extensions {#compat_wgl}
+
+The WGL API is used to create OpenGL contexts on Microsoft Windows and other
+implementations of the Win32 API, such as Wine.
+
+GLFW uses either the `WGL_EXT_extension_string` or the
+`WGL_ARB_extension_string` extension to check for the presence of all other WGL
+extensions listed below.  If both are available, the EXT one is preferred.  If
+neither is available, no other extensions are used and many GLFW features
+related to context creation will have no effect or cause errors when used.
+
+GLFW uses the `WGL_EXT_swap_control` extension to provide vertical retrace
+synchronization (or _vsync_).  Where this extension is unavailable, calling @ref
+glfwSwapInterval will have no effect.
+
+GLFW uses the `WGL_ARB_pixel_format` and `WGL_ARB_multisample` extensions to
+create contexts with multisampling anti-aliasing.  Where these extensions are
+unavailable, the `GLFW_SAMPLES` hint will have no effect.
+
+GLFW uses the `WGL_ARB_create_context` extension when available, even when
+creating OpenGL contexts of version 2.1 and below.  Where this extension is
+unavailable, the `GLFW_CONTEXT_VERSION_MAJOR` and `GLFW_CONTEXT_VERSION_MINOR`
+hints will only be partially supported, the `GLFW_CONTEXT_DEBUG` hint will have
+no effect, and setting the `GLFW_OPENGL_PROFILE` or `GLFW_OPENGL_FORWARD_COMPAT`
+hints to `GLFW_TRUE` will cause @ref glfwCreateWindow to fail.
+
+GLFW uses the `WGL_ARB_create_context_profile` extension to provide support for
+context profiles.  Where this extension is unavailable, setting the
+`GLFW_OPENGL_PROFILE` hint to anything but `GLFW_OPENGL_ANY_PROFILE` will cause
+@ref glfwCreateWindow to fail.
+
+GLFW uses the `WGL_ARB_context_flush_control` extension to provide control over
+whether a context is flushed when it is released (made non-current).  Where this
+extension is unavailable, the `GLFW_CONTEXT_RELEASE_BEHAVIOR` hint will have no
+effect and the context will always be flushed when released.
+
+GLFW uses the `WGL_ARB_framebuffer_sRGB` and `WGL_EXT_framebuffer_sRGB`
+extensions to provide support for sRGB framebuffers.  When both of these
+extensions are unavailable, the `GLFW_SRGB_CAPABLE` hint will have no effect.
+
+
+## OpenGL on macOS {#compat_osx}
+
+Support for OpenGL 3.2 and above was introduced with OS X 10.7 and even then
+only forward-compatible, core profile contexts are supported.  Support for
+OpenGL 4.1 was introduced with OS X 10.9, also limited to forward-compatible,
+core profile contexts.  There is also still no mechanism for requesting debug
+contexts or no-error contexts.  Versions of Mac OS X earlier than 10.7 support
+at most OpenGL version 2.1.
+
+Because of this, on OS X 10.7 and later, the `GLFW_CONTEXT_VERSION_MAJOR` and
+`GLFW_CONTEXT_VERSION_MINOR` hints will cause @ref glfwCreateWindow to fail if
+given version 3.0 or 3.1.  The `GLFW_OPENGL_PROFILE` hint must be set to
+`GLFW_OPENGL_CORE_PROFILE` when creating OpenGL 3.2 and later contexts.  The
+`GLFW_CONTEXT_DEBUG` and `GLFW_CONTEXT_NO_ERROR` hints are ignored.
+
+Also, on Mac OS X 10.6 and below, the `GLFW_CONTEXT_VERSION_MAJOR` and
+`GLFW_CONTEXT_VERSION_MINOR` hints will fail if given a version above 2.1,
+setting the `GLFW_OPENGL_PROFILE` or `GLFW_OPENGL_FORWARD_COMPAT` hints to
+a non-default value will cause @ref glfwCreateWindow to fail and the
+`GLFW_CONTEXT_DEBUG` hint is ignored.
+
+
+## Vulkan loader and API {#compat_vulkan}
+
+By default, GLFW uses the standard system-wide Vulkan loader to access the
+Vulkan API on all platforms except macOS.  This is installed by both graphics
+drivers and Vulkan SDKs.  If either the loader or at least one minimally
+functional ICD is missing, @ref glfwVulkanSupported will return `GLFW_FALSE` and
+all other Vulkan-related functions will fail with an @ref GLFW_API_UNAVAILABLE
+error.
+
+
+## Vulkan WSI extensions {#compat_wsi}
+
+The Vulkan WSI extensions are used to create Vulkan surfaces for GLFW windows on
+all supported platforms.
+
+GLFW uses the `VK_KHR_surface` and `VK_KHR_win32_surface` extensions to create
+surfaces on Microsoft Windows.  If any of these extensions are not available,
+@ref glfwGetRequiredInstanceExtensions will return an empty list and window
+surface creation will fail.
+
+GLFW uses the `VK_KHR_surface` and either the `VK_MVK_macos_surface` or
+`VK_EXT_metal_surface` extensions to create surfaces on macOS.  If any of these
+extensions are not available, @ref glfwGetRequiredInstanceExtensions will
+return an empty list and window surface creation will fail.
+
+GLFW uses the `VK_KHR_surface` and either the `VK_KHR_xlib_surface` or
+`VK_KHR_xcb_surface` extensions to create surfaces on X11.  If `VK_KHR_surface`
+or both `VK_KHR_xlib_surface` and `VK_KHR_xcb_surface` are not available, @ref
+glfwGetRequiredInstanceExtensions will return an empty list and window surface
+creation will fail.
+
+GLFW uses the `VK_KHR_surface` and `VK_KHR_wayland_surface` extensions to create
+surfaces on Wayland.  If any of these extensions are not available, @ref
+glfwGetRequiredInstanceExtensions will return an empty list and window surface
+creation will fail.

+# Compiling GLFW {#compile_guide}
+
+[TOC]
+
+This is about compiling the GLFW library itself.  For information on how to
+build applications that use GLFW, see @ref build_guide.
+
+GLFW uses some C99 features and does not support Visual Studio 2012 and earlier.
+
+
+## Using CMake {#compile_cmake}
+
+GLFW behaves like most other libraries that use CMake so this guide mostly
+describes the standard configure, generate and compile sequence.  If you are already
+familiar with this from other projects, you may want to focus on the @ref
+compile_deps and @ref compile_options sections for GLFW-specific information.
+
+GLFW uses [CMake](https://cmake.org/) to generate project files or makefiles
+for your chosen development environment.  To compile GLFW, first generate these
+files with CMake and then use them to compile the GLFW library. 
+
+If you are on Windows and macOS you can [download
+CMake](https://cmake.org/download/) from their site.
+
+If you are on a Unix-like system such as Linux, FreeBSD or Cygwin or have
+a package system like Fink, MacPorts or Homebrew, you can install its CMake
+package.
+
+CMake is a complex tool and this guide will only show a few of the possible ways
+to set up and compile GLFW.  The CMake project has their own much more detailed
+[CMake user guide][cmake-guide] that includes everything in this guide not
+specific to GLFW.  It may be a useful companion to this one.
+
+[cmake-guide]: https://cmake.org/cmake/help/latest/guide/user-interaction/
+
+
+### Installing dependencies {#compile_deps}
+
+The C/C++ development environments in Visual Studio, Xcode and MinGW come with
+all necessary dependencies for compiling GLFW, but on Unix-like systems like
+Linux and FreeBSD you will need a few extra packages.
+
+
+#### Dependencies for Wayland and X11 {#compile_deps_wayland}
+
+By default, both the Wayland and X11 backends are enabled on Linux and other Unix-like
+systems (except macOS).  To disable one or both of these, set the @ref GLFW_BUILD_WAYLAND
+or @ref GLFW_BUILD_X11 CMake options in the next step when generating build files.
+
+To compile GLFW for both Wayland and X11, you need to have the X11, Wayland and xkbcommon
+development packages installed.  On some systems a few other packages are also required.
+None of the development packages above are needed to build or run programs that use an
+already compiled GLFW library.
+
+On Debian and derivatives like Ubuntu and Linux Mint you will need the `libwayland-dev`
+and `libxkbcommon-dev` packages to compile for Wayland and the `xorg-dev` meta-package to
+compile for X11.  These will pull in all other dependencies.
+
+```sh
+sudo apt install libwayland-dev libxkbcommon-dev xorg-dev
+```
+
+On Fedora and derivatives like Red Hat you will need the `wayland-devel` and
+`libxkbcommon-devel` packages to compile for Wayland and the `libXcursor-devel`,
+`libXi-devel`, `libXinerama-devel` and `libXrandr-devel` packages to compile for X11.
+These will pull in all other dependencies.
+
+```sh
+sudo dnf install wayland-devel libxkbcommon-devel libXcursor-devel libXi-devel libXinerama-devel libXrandr-devel
+```
+
+On FreeBSD you will need the `wayland`, `libxkbcommon` and `evdev-proto` packages to
+compile for Wayland.  The X11 headers are installed along the end-user X11 packages, so if
+you have an X server running you should have the headers as well.  If not, install the
+`xorgproto` package to compile for X11.
+
+```sh
+pkg install wayland libxkbcommon evdev-proto xorgproto
+```
+
+On Cygwin Wayland is not supported but you will need the `libXcursor-devel`,
+`libXi-devel`, `libXinerama-devel`, `libXrandr-devel` and `libXrender-devel` packages to
+compile for X11.  These can be found in the Libs section of the GUI installer and will
+pull in all other dependencies.
+
+Once you have the required dependencies, move on to @ref compile_generate.
+
+
+### Generating build files with CMake {#compile_generate}
+
+Once you have all necessary dependencies it is time to generate the project
+files or makefiles for your development environment.  CMake needs two paths for
+this:
+
+ - the path to the root directory of the GLFW source tree (not its `src`
+   subdirectory)
+ - the path to the directory where the generated build files and compiled
+   binaries will be placed
+
+If these are the same, it is called an in-tree build, otherwise it is called an
+out-of-tree build.
+
+Out-of-tree builds are recommended as they avoid cluttering up the source tree.
+They also allow you to have several build directories for different
+configurations all using the same source tree.
+
+A common pattern when building a single configuration is to have a build
+directory named `build` in the root of the source tree.
+
+
+#### Generating with the CMake GUI {#compile_generate_gui}
+
+Start the CMake GUI and set the paths to the source and build directories
+described above.  Then press _Configure_ and _Generate_.
+
+If you wish change any CMake variables in the list, press _Configure_ and then
+_Generate_ to have the new values take effect.  The variable list will be
+populated after the first configure step.
+
+By default, GLFW will use Wayland and X11 on Linux and other Unix-like systems other than
+macOS.  To disable support for one or both of these, set the @ref GLFW_BUILD_WAYLAND
+and/or @ref GLFW_BUILD_X11 option in the GLFW section of the variable list, then apply the
+new value as described above.
+
+Once you have generated the project files or makefiles for your chosen
+development environment, move on to @ref compile_compile.
+
+
+#### Generating with command-line CMake {#compile_generate_cli}
+
+To make a build directory, pass the source and build directories to the `cmake`
+command.  These can be relative or absolute paths.  The build directory is
+created if it doesn't already exist.
+
+```sh
+cmake -S path/to/glfw -B path/to/build
+```
+
+It is common to name the build directory `build` and place it in the root of the
+source tree when only planning to build a single configuration.
+
+```sh
+cd path/to/glfw
+cmake -S . -B build
+```
+
+Without other flags these will generate Visual Studio project files on Windows
+and makefiles on other platforms.  You can choose other targets using the `-G`
+flag.
+
+```sh
+cmake -S path/to/glfw -B path/to/build -G Xcode
+```
+
+By default, GLFW will use Wayland and X11 on Linux and other Unix-like systems other than
+macOS.  To disable support for one or both of these, set the @ref GLFW_BUILD_WAYLAND
+and/or @ref GLFW_BUILD_X11 CMake option.
+
+```sh
+cmake -S path/to/glfw -B path/to/build -D GLFW_BUILD_X11=0
+```
+
+Once you have generated the project files or makefiles for your chosen
+development environment, move on to @ref compile_compile.
+
+
+### Compiling the library {#compile_compile}
+
+You should now have all required dependencies and the project files or makefiles
+necessary to compile GLFW.  Go ahead and compile the actual GLFW library with
+these files as you would with any other project.
+
+With Visual Studio open `GLFW.sln` and use the Build menu.  With Xcode open
+`GLFW.xcodeproj` and use the Project menu.
+
+With Linux, macOS and other forms of Unix, run `make`.
+
+```sh
+cd path/to/build
+make
+```
+
+With MinGW, it is `mingw32-make`.
+
+```sh
+cd path/to/build
+mingw32-make
+```
+
+Any CMake build directory can also be built with the `cmake` command and the
+`--build` flag.
+
+```sh
+cmake --build path/to/build
+```
+
+This will run the platform specific build tool the directory was generated for.
+
+Once the GLFW library is compiled you are ready to build your application,
+linking it to the GLFW library.  See @ref build_guide for more information.
+
+
+## CMake options {#compile_options}
+
+The CMake files for GLFW provide a number of options, although not all are
+available on all supported platforms.  Some of these are de facto standards
+among projects using CMake and so have no `GLFW_` prefix.
+
+If you are using the GUI version of CMake, these are listed and can be changed
+from there.  If you are using the command-line version of CMake you can use the
+`ccmake` ncurses GUI to set options.  Some package systems like Ubuntu and other
+distributions based on Debian GNU/Linux have this tool in a separate
+`cmake-curses-gui` package.
+
+Finally, if you don't want to use any GUI, you can set options from the `cmake`
+command-line with the `-D` flag.
+
+```sh
+cmake -S path/to/glfw -B path/to/build -D BUILD_SHARED_LIBS=ON
+```
+
+
+### Shared CMake options {#compile_options_shared}
+
+@anchor BUILD_SHARED_LIBS
+__BUILD_SHARED_LIBS__ determines whether GLFW is built as a static library or as
+a DLL / shared library / dynamic library.  This is disabled by default,
+producing a static GLFW library.  This variable has no `GLFW_` prefix because it
+is defined by CMake.  If you want to change the library only for GLFW when it is
+part of a larger project, see @ref GLFW_LIBRARY_TYPE.
+
+@anchor GLFW_LIBRARY_TYPE
+__GLFW_LIBRARY_TYPE__ allows you to override @ref BUILD_SHARED_LIBS only for
+GLFW, without affecting other libraries in a larger project.  When set, the
+value of this option must be a valid CMake library type.  Set it to `STATIC` to
+build GLFW as a static library, `SHARED` to build it as a shared library
+/ dynamic library / DLL, or `OBJECT` to make GLFW a CMake object library.
+
+@anchor GLFW_BUILD_EXAMPLES
+__GLFW_BUILD_EXAMPLES__ determines whether the GLFW examples are built
+along with the library.  This is enabled by default unless GLFW is being built
+as a subproject of a larger CMake project.
+
+@anchor GLFW_BUILD_TESTS
+__GLFW_BUILD_TESTS__ determines whether the GLFW test programs are
+built along with the library.  This is enabled by default unless GLFW is being
+built as a subproject of a larger CMake project.
+
+@anchor GLFW_BUILD_DOCS
+__GLFW_BUILD_DOCS__ determines whether the GLFW documentation is built along
+with the library.  This is enabled by default if
+[Doxygen](https://www.doxygen.nl/) is found by CMake during configuration.
+
+
+### Win32 specific CMake options {#compile_options_win32}
+
+@anchor GLFW_BUILD_WIN32
+__GLFW_BUILD_WIN32__ determines whether to include support for Win32 when compiling the
+library.  This option is only available when compiling for Windows.  This is enabled by
+default.
+
+@anchor USE_MSVC_RUNTIME_LIBRARY_DLL
+__USE_MSVC_RUNTIME_LIBRARY_DLL__ determines whether to use the DLL version or the
+static library version of the Visual C++ runtime library.  When enabled, the
+DLL version of the Visual C++ library is used.  This is enabled by default.
+
+On CMake 3.15 and later you can set the standard CMake [CMAKE_MSVC_RUNTIME_LIBRARY][]
+variable instead of this GLFW-specific option.
+
+[CMAKE_MSVC_RUNTIME_LIBRARY]: https://cmake.org/cmake/help/latest/variable/CMAKE_MSVC_RUNTIME_LIBRARY.html
+
+@anchor GLFW_USE_HYBRID_HPG
+__GLFW_USE_HYBRID_HPG__ determines whether to export the `NvOptimusEnablement` and
+`AmdPowerXpressRequestHighPerformance` symbols, which force the use of the
+high-performance GPU on Nvidia Optimus and AMD PowerXpress systems.  These symbols
+need to be exported by the EXE to be detected by the driver, so the override
+will not work if GLFW is built as a DLL.  This is disabled by default, letting
+the operating system and driver decide.
+
+
+### macOS specific CMake options {#compile_options_macos}
+
+@anchor GLFW_BUILD_COCOA
+__GLFW_BUILD_COCOA__ determines whether to include support for Cocoa when compiling the
+library.  This option is only available when compiling for macOS.  This is enabled by
+default.
+
+
+### Unix-like system specific CMake options {#compile_options_unix}
+
+@anchor GLFW_BUILD_WAYLAND
+__GLFW_BUILD_WAYLAND__ determines whether to include support for Wayland when compiling
+the library.  This option is only available when compiling for Linux and other Unix-like
+systems other than macOS.  This is enabled by default.
+
+@anchor GLFW_BUILD_X11
+__GLFW_BUILD_X11__ determines whether to include support for X11 when compiling the
+library.  This option is only available when compiling for Linux and other Unix-like
+systems other than macOS.  This is enabled by default.
+
+
+## Cross-compilation with CMake and MinGW {#compile_mingw_cross}
+
+Both Cygwin and many Linux distributions have MinGW or MinGW-w64 packages.  For
+example, Cygwin has the `mingw64-i686-gcc` and `mingw64-x86_64-gcc` packages
+for 32- and 64-bit version of MinGW-w64, while Debian GNU/Linux and derivatives
+like Ubuntu have the `mingw-w64` package for both.
+
+GLFW has CMake toolchain files in the `CMake` subdirectory that set up
+cross-compilation of Windows binaries.  To use these files you set the
+`CMAKE_TOOLCHAIN_FILE` CMake variable with the `-D` flag add an option when
+configuring and generating the build files.
+
+```sh
+cmake -S path/to/glfw -B path/to/build -D CMAKE_TOOLCHAIN_FILE=path/to/file
+```
+
+The exact toolchain file to use depends on the prefix used by the MinGW or
+MinGW-w64 binaries on your system.  You can usually see this in the /usr
+directory.  For example, both the Ubuntu and Cygwin MinGW-w64 packages have
+`/usr/x86_64-w64-mingw32` for the 64-bit compilers, so the correct invocation
+would be:
+
+```sh
+cmake -S path/to/glfw -B path/to/build -D CMAKE_TOOLCHAIN_FILE=CMake/x86_64-w64-mingw32.cmake
+```
+
+The path to the toolchain file is relative to the path to the GLFW source tree
+passed to the `-S` flag, not to the current directory.
+
+For more details see the [CMake toolchain guide][cmake-toolchains].
+
+[cmake-toolchains]: https://cmake.org/cmake/help/latest/manual/cmake-toolchains.7.html
+
+
+## Compiling GLFW manually {#compile_manual}
+
+If you wish to compile GLFW without its CMake build environment then you will have to do
+at least some platform-detection yourself.  There are preprocessor macros for
+enabling support for the platforms (window systems) available.  There are also optional,
+platform-specific macros for various features.
+
+When building, GLFW will expect the necessary configuration macros to be defined
+on the command-line.  The GLFW CMake files set these as private compile
+definitions on the GLFW target but if you compile the GLFW sources manually you
+will need to define them yourself.
+
+The window system is used to create windows, handle input, monitors, gamma ramps and
+clipboard.  The options are:
+
+ - @b _GLFW_COCOA to use the Cocoa frameworks
+ - @b _GLFW_WIN32 to use the Win32 API
+ - @b _GLFW_WAYLAND to use the Wayland protocol
+ - @b _GLFW_X11 to use the X Window System
+
+The @b _GLFW_WAYLAND and @b _GLFW_X11 macros may be combined and produces a library that
+attempts to detect the appropriate platform at initialization.
+
+If you are building GLFW as a shared library / dynamic library / DLL then you
+must also define @b _GLFW_BUILD_DLL.  Otherwise, you must not define it.
+
+If you are using a custom name for the Vulkan, EGL, GLX, OSMesa, OpenGL, GLESv1
+or GLESv2 library, you can override the default names by defining those you need
+of @b _GLFW_VULKAN_LIBRARY, @b _GLFW_EGL_LIBRARY, @b _GLFW_GLX_LIBRARY, @b
+_GLFW_OSMESA_LIBRARY, @b _GLFW_OPENGL_LIBRARY, @b _GLFW_GLESV1_LIBRARY and @b
+_GLFW_GLESV2_LIBRARY.  Otherwise, GLFW will use the built-in default names.
+
+@note None of the @ref build_macros may be defined during the compilation of
+GLFW.  If you define any of these in your build files, make sure they are not
+applied to the GLFW sources.

+# Context guide {#context_guide}
+
+[TOC]
+
+This guide introduces the OpenGL and OpenGL ES context related functions of
+GLFW.  For details on a specific function in this category, see the @ref
+context.  There are also guides for the other areas of the GLFW API.
+
+ - @ref intro_guide
+ - @ref window_guide
+ - @ref vulkan_guide
+ - @ref monitor_guide
+ - @ref input_guide
+
+
+## Context objects {#context_object}
+
+A window object encapsulates both a top-level window and an OpenGL or OpenGL ES
+context.  It is created with @ref glfwCreateWindow and destroyed with @ref
+glfwDestroyWindow or @ref glfwTerminate.  See @ref window_creation for more
+information.
+
+As the window and context are inseparably linked, the window object also serves
+as the context handle.
+
+To test the creation of various kinds of contexts and see their properties, run
+the `glfwinfo` test program.
+
+@note Vulkan does not have a context and the Vulkan instance is created via the
+Vulkan API itself.  If you will be using Vulkan to render to a window, disable
+context creation by setting the [GLFW_CLIENT_API](@ref GLFW_CLIENT_API_hint)
+hint to `GLFW_NO_API`.  For more information, see the @ref vulkan_guide.
+
+
+### Context creation hints {#context_hints}
+
+There are a number of hints, specified using @ref glfwWindowHint, related to
+what kind of context is created.  See
+[context related hints](@ref window_hints_ctx) in the window guide.
+
+
+### Context object sharing {#context_sharing}
+
+When creating a window and its OpenGL or OpenGL ES context with @ref
+glfwCreateWindow, you can specify another window whose context the new one
+should share its objects (textures, vertex and element buffers, etc.) with.
+
+```c
+GLFWwindow* second_window = glfwCreateWindow(640, 480, "Second Window", NULL, first_window);
+```
+
+Object sharing is implemented by the operating system and graphics driver.  On
+platforms where it is possible to choose which types of objects are shared, GLFW
+requests that all types are shared.
+
+See the relevant chapter of the [OpenGL](https://www.opengl.org/registry/) or
+[OpenGL ES](https://www.khronos.org/opengles/) reference documents for more
+information.  The name and number of this chapter unfortunately varies between
+versions and APIs, but has at times been named _Shared Objects and Multiple
+Contexts_.
+
+GLFW comes with a bare-bones object sharing example program called `sharing`.
+
+
+### Offscreen contexts {#context_offscreen}
+
+GLFW doesn't support creating contexts without an associated window.  However,
+contexts with hidden windows can be created with the
+[GLFW_VISIBLE](@ref GLFW_VISIBLE_hint) window hint.
+
+```c
+glfwWindowHint(GLFW_VISIBLE, GLFW_FALSE);
+
+GLFWwindow* offscreen_context = glfwCreateWindow(640, 480, "", NULL, NULL);
+```
+
+The window never needs to be shown and its context can be used as a plain
+offscreen context.  Depending on the window manager, the size of a hidden
+window's framebuffer may not be usable or modifiable, so framebuffer
+objects are recommended for rendering with such contexts.
+
+You should still [process events](@ref events) as long as you have at least one
+window, even if none of them are visible.
+
+
+### Windows without contexts {#context_less}
+
+You can disable context creation by setting the
+[GLFW_CLIENT_API](@ref GLFW_CLIENT_API_hint) hint to `GLFW_NO_API`.
+
+Windows without contexts should not be passed to @ref glfwMakeContextCurrent or
+@ref glfwSwapBuffers.  Doing this generates a @ref GLFW_NO_WINDOW_CONTEXT error.
+
+
+## Current context {#context_current}
+
+Before you can make OpenGL or OpenGL ES calls, you need to have a current
+context of the correct type.  A context can only be current for a single thread
+at a time, and a thread can only have a single context current at a time.
+
+When moving a context between threads, you must make it non-current on the old
+thread before making it current on the new one.
+
+The context of a window is made current with @ref glfwMakeContextCurrent.
+
+```c
+glfwMakeContextCurrent(window);
+```
+
+The window of the current context is returned by @ref glfwGetCurrentContext.
+
+```c
+GLFWwindow* window = glfwGetCurrentContext();
+```
+
+The following GLFW functions require a context to be current.  Calling any these
+functions without a current context will generate a @ref GLFW_NO_CURRENT_CONTEXT
+error.
+
+ - @ref glfwSwapInterval
+ - @ref glfwExtensionSupported
+ - @ref glfwGetProcAddress
+
+
+## Buffer swapping {#context_swap}
+
+See @ref buffer_swap in the window guide.
+
+
+## OpenGL and OpenGL ES extensions {#context_glext}
+
+One of the benefits of OpenGL and OpenGL ES is their extensibility.
+Hardware vendors may include extensions in their implementations that extend the
+API before that functionality is included in a new version of the OpenGL or
+OpenGL ES specification, and some extensions are never included and remain
+as extensions until they become obsolete.
+
+An extension is defined by:
+
+- An extension name (e.g. `GL_ARB_gl_spirv`)
+- New OpenGL tokens (e.g. `GL_SPIR_V_BINARY_ARB`)
+- New OpenGL functions (e.g. `glSpecializeShaderARB`)
+
+Note the `ARB` affix, which stands for Architecture Review Board and is used
+for official extensions.  The extension above was created by the ARB, but there
+are many different affixes, like `NV` for Nvidia and `AMD` for, well, AMD.  Any
+group may also use the generic `EXT` affix.  Lists of extensions, together with
+their specifications, can be found at the
+[OpenGL Registry](https://www.opengl.org/registry/) and
+[OpenGL ES Registry](https://www.khronos.org/registry/gles/).
+
+
+### Loading extension with a loader library {#context_glext_auto}
+
+An extension loader library is the easiest and best way to access both OpenGL and
+OpenGL ES extensions and modern versions of the core OpenGL or OpenGL ES APIs.
+They will take care of all the details of declaring and loading everything you
+need.  One such library is [glad](https://github.com/Dav1dde/glad) and there are
+several others.
+
+The following example will use glad but all extension loader libraries work
+similarly.
+
+First you need to generate the source files using the glad Python script.  This
+example generates a loader for any version of OpenGL, which is the default for
+both GLFW and glad, but loaders for OpenGL ES, as well as loaders for specific
+API versions and extension sets can be generated.  The generated files are
+written to the `output` directory.
+
+```sh
+python main.py --generator c --no-loader --out-path output
+```
+
+The `--no-loader` option is added because GLFW already provides a function for
+loading OpenGL and OpenGL ES function pointers, one that automatically uses the
+selected context creation API, and glad can call this instead of having to
+implement its own.  There are several other command-line options as well.  See
+the glad documentation for details.
+
+Add the generated `output/src/glad.c`, `output/include/glad/glad.h` and
+`output/include/KHR/khrplatform.h` files to your build.  Then you need to
+include the glad header file, which will replace the OpenGL header of your
+development environment.  By including the glad header before the GLFW header,
+it suppresses the development environment's OpenGL or OpenGL ES header.
+
+```c
+#include <glad/glad.h>
+#include <GLFW/glfw3.h>
+```
+
+Finally, you need to initialize glad once you have a suitable current context.
+
+```c
+window = glfwCreateWindow(640, 480, "My Window", NULL, NULL);
+if (!window)
+{
+    ...
+}
+
+glfwMakeContextCurrent(window);
+
+gladLoadGLLoader((GLADloadproc) glfwGetProcAddress);
+```
+
+Once glad has been loaded, you have access to all OpenGL core and extension
+functions supported by both the context you created and the glad loader you
+generated. After that, you are ready to start rendering.
+
+You can specify a minimum required OpenGL or OpenGL ES version with
+[context hints](@ref window_hints_ctx).  If your needs are more complex, you can
+check the actual OpenGL or OpenGL ES version with
+[context attributes](@ref window_attribs_ctx), or you can check whether
+a specific version is supported by the current context with the
+`GLAD_GL_VERSION_x_x` booleans.
+
+```c
+if (GLAD_GL_VERSION_3_2)
+{
+    // Call OpenGL 3.2+ specific code
+}
+```
+
+To check whether a specific extension is supported, use the `GLAD_GL_xxx`
+booleans.
+
+```c
+if (GLAD_GL_ARB_gl_spirv)
+{
+    // Use GL_ARB_gl_spirv
+}
+```
+
+
+### Loading extensions manually {#context_glext_manual}
+
+__Do not use this technique__ unless it is absolutely necessary.  An
+[extension loader library](@ref context_glext_auto) will save you a ton of
+tedious, repetitive, error prone work.
+
+To use a certain extension, you must first check whether the context supports
+that extension and then, if it introduces new functions, retrieve the pointers
+to those functions.  GLFW provides @ref glfwExtensionSupported and @ref
+glfwGetProcAddress for manual loading of extensions and new API functions.
+
+This section will demonstrate manual loading of OpenGL extensions.  The loading
+of OpenGL ES extensions is identical except for the name of the extension header.
+
+
+#### The glext.h header {#context_glext_header}
+
+The `glext.h` extension header is a continually updated file that defines the
+interfaces for all OpenGL extensions.  The latest version of this can always be
+found at the [OpenGL Registry](https://www.opengl.org/registry/).  There are also
+extension headers for the various versions of OpenGL ES at the
+[OpenGL ES Registry](https://www.khronos.org/registry/gles/).  It it strongly
+recommended that you use your own copy of the extension header, as the one
+included in your development environment may be several years out of date and
+may not include the extensions you wish to use.
+
+The header defines function pointer types for all functions of all extensions it
+supports.  These have names like `PFNGLSPECIALIZESHADERARBPROC` (for
+`glSpecializeShaderARB`), i.e. the name is made uppercase and `PFN` (pointer
+to function) and `PROC` (procedure) are added to the ends.
+
+To include the extension header, define @ref GLFW_INCLUDE_GLEXT before including
+the GLFW header.
+
+```c
+#define GLFW_INCLUDE_GLEXT
+#include <GLFW/glfw3.h>
+```
+
+
+#### Checking for extensions {#context_glext_string}
+
+A given machine may not actually support the extension (it may have older
+drivers or a graphics card that lacks the necessary hardware features), so it
+is necessary to check at run-time whether the context supports the extension.
+This is done with @ref glfwExtensionSupported.
+
+```c
+if (glfwExtensionSupported("GL_ARB_gl_spirv"))
+{
+    // The extension is supported by the current context
+}
+```
+
+The argument is a null terminated ASCII string with the extension name.  If the
+extension is supported, @ref glfwExtensionSupported returns `GLFW_TRUE`,
+otherwise it returns `GLFW_FALSE`.
+
+
+#### Fetching function pointers {#context_glext_proc}
+
+Many extensions, though not all, require the use of new OpenGL functions.
+These functions often do not have entry points in the client API libraries of
+your operating system, making it necessary to fetch them at run time.  You can
+retrieve pointers to these functions with @ref glfwGetProcAddress.
+
+```c
+PFNGLSPECIALIZESHADERARBPROC pfnSpecializeShaderARB = glfwGetProcAddress("glSpecializeShaderARB");
+```
+
+In general, you should avoid giving the function pointer variables the (exact)
+same name as the function, as this may confuse your linker.  Instead, you can
+use a different prefix, like above, or some other naming scheme.
+
+Now that all the pieces have been introduced, here is what they might look like
+when used together.
+
+```c
+#define GLFW_INCLUDE_GLEXT
+#include <GLFW/glfw3.h>
+
+#define glSpecializeShaderARB pfnSpecializeShaderARB
+PFNGLSPECIALIZESHADERARBPROC pfnSpecializeShaderARB;
+
+// Flag indicating whether the extension is supported
+int has_ARB_gl_spirv = 0;
+
+void load_extensions(void)
+{
+    if (glfwExtensionSupported("GL_ARB_gl_spirv"))
+    {
+        pfnSpecializeShaderARB = (PFNGLSPECIALIZESHADERARBPROC)
+            glfwGetProcAddress("glSpecializeShaderARB");
+        has_ARB_gl_spirv = 1;
+    }
+}
+

+# Input guide {#input_guide}
+
+[TOC]
+
+This guide introduces the input related functions of GLFW.  For details on
+a specific function in this category, see the @ref input.  There are also guides
+for the other areas of GLFW.
+
+ - @ref intro_guide
+ - @ref window_guide
+ - @ref context_guide
+ - @ref vulkan_guide
+ - @ref monitor_guide
+
+GLFW provides many kinds of input.  While some can only be polled, like time, or
+only received via callbacks, like scrolling, many provide both callbacks and
+polling.  Callbacks are more work to use than polling but is less CPU intensive
+and guarantees that you do not miss state changes.
+
+All input callbacks receive a window handle.  By using the
+[window user pointer](@ref window_userptr), you can access non-global structures
+or objects from your callbacks.
+
+To get a better feel for how the various events callbacks behave, run the
+`events` test program.  It registers every callback supported by GLFW and prints
+out all arguments provided for every event, along with time and sequence
+information.
+
+
+## Event processing {#events}
+
+GLFW needs to poll the window system for events both to provide input to the
+application and to prove to the window system that the application hasn't locked
+up.  Event processing is normally done each frame after
+[buffer swapping](@ref buffer_swap).  Even when you have no windows, event
+polling needs to be done in order to receive monitor and joystick connection
+events.
+
+There are three functions for processing pending events.  @ref glfwPollEvents,
+processes only those events that have already been received and then returns
+immediately.
+
+```c
+glfwPollEvents();
+```
+
+This is the best choice when rendering continuously, like most games do.
+
+If you only need to update the contents of the window when you receive new
+input, @ref glfwWaitEvents is a better choice.
+
+```c
+glfwWaitEvents();
+```
+
+It puts the thread to sleep until at least one event has been received and then
+processes all received events.  This saves a great deal of CPU cycles and is
+useful for, for example, editing tools.
+
+If you want to wait for events but have UI elements or other tasks that need
+periodic updates, @ref glfwWaitEventsTimeout lets you specify a timeout.
+
+```c
+glfwWaitEventsTimeout(0.7);
+```
+
+It puts the thread to sleep until at least one event has been received, or until
+the specified number of seconds have elapsed.  It then processes any received
+events.
+
+If the main thread is sleeping in @ref glfwWaitEvents, you can wake it from
+another thread by posting an empty event to the event queue with @ref
+glfwPostEmptyEvent.
+
+```c
+glfwPostEmptyEvent();
+```
+
+Do not assume that callbacks will _only_ be called in response to the above
+functions.  While it is necessary to process events in one or more of the ways
+above, window systems that require GLFW to register callbacks of its own can
+pass events to GLFW in response to many window system function calls.  GLFW will
+pass those events on to the application callbacks before returning.
+
+For example, on Windows the system function that @ref glfwSetWindowSize is
+implemented with will send window size events directly to the event callback
+that every window has and that GLFW implements for its windows.  If you have set
+a [window size callback](@ref window_size) GLFW will call it in turn with the
+new size before everything returns back out of the @ref glfwSetWindowSize call.
+
+
+## Keyboard input {#input_keyboard}
+
+GLFW divides keyboard input into two categories; key events and character
+events.  Key events relate to actual physical keyboard keys, whereas character
+events relate to the text that is generated by pressing some of them.
+
+Keys and characters do not map 1:1.  A single key press may produce several
+characters, and a single character may require several keys to produce.  This
+may not be the case on your machine, but your users are likely not all using the
+same keyboard layout, input method or even operating system as you.
+
+
+### Key input {#input_key}
+
+If you wish to be notified when a physical key is pressed or released or when it
+repeats, set a key callback.
+
+```c
+glfwSetKeyCallback(window, key_callback);
+```
+
+The callback function receives the [keyboard key](@ref keys), platform-specific
+scancode, key action and [modifier bits](@ref mods).
+
+```c
+void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods)
+{
+    if (key == GLFW_KEY_E && action == GLFW_PRESS)
+        activate_airship();
+}
+```
+
+The action is one of `GLFW_PRESS`, `GLFW_REPEAT` or `GLFW_RELEASE`.  Events with
+`GLFW_PRESS` and `GLFW_RELEASE` actions are emitted for every key press.  Most
+keys will also emit events with `GLFW_REPEAT` actions while a key is held down.
+
+Note that many keyboards have a limit on how many keys being simultaneous held
+down that they can detect.  This limit is called
+[key rollover](https://en.wikipedia.org/wiki/Key_rollover).
+
+Key events with `GLFW_REPEAT` actions are intended for text input.  They are
+emitted at the rate set in the user's keyboard settings.  At most one key is
+repeated even if several keys are held down.  `GLFW_REPEAT` actions should not
+be relied on to know which keys are being held down or to drive animation.
+Instead you should either save the state of relevant keys based on `GLFW_PRESS`
+and `GLFW_RELEASE` actions, or call @ref glfwGetKey, which provides basic cached
+key state.
+
+The key will be one of the existing [key tokens](@ref keys), or
+`GLFW_KEY_UNKNOWN` if GLFW lacks a token for it, for example _E-mail_ and _Play_
+keys.
+
+The scancode is unique for every key, regardless of whether it has a key token.
+Scancodes are platform-specific but consistent over time, so keys will have
+different scancodes depending on the platform but they are safe to save to disk.
+You can query the scancode for any [key token](@ref keys) supported on the
+current platform with @ref glfwGetKeyScancode.
+
+```c
+const int scancode = glfwGetKeyScancode(GLFW_KEY_X);
+set_key_mapping(scancode, swap_weapons);
+```
+
+The last reported state for every physical key with a [key token](@ref keys) is
+also saved in per-window state arrays that can be polled with @ref glfwGetKey.
+
+```c
+int state = glfwGetKey(window, GLFW_KEY_E);
+if (state == GLFW_PRESS)
+{
+    activate_airship();
+}
+```
+
+The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`.
+
+This function only returns cached key event state.  It does not poll the
+system for the current state of the physical key.  It also does not provide any
+key repeat information.
+
+@anchor GLFW_STICKY_KEYS
+Whenever you poll state, you risk missing the state change you are looking for.
+If a pressed key is released again before you poll its state, you will have
+missed the key press.  The recommended solution for this is to use a
+key callback, but there is also the `GLFW_STICKY_KEYS` input mode.
+
+```c
+glfwSetInputMode(window, GLFW_STICKY_KEYS, GLFW_TRUE);
+```
+
+When sticky keys mode is enabled, the pollable state of a key will remain
+`GLFW_PRESS` until the state of that key is polled with @ref glfwGetKey.  Once
+it has been polled, if a key release event had been processed in the meantime,
+the state will reset to `GLFW_RELEASE`, otherwise it will remain `GLFW_PRESS`.
+
+@anchor GLFW_LOCK_KEY_MODS
+If you wish to know what the state of the Caps Lock and Num Lock keys was when
+input events were generated, set the `GLFW_LOCK_KEY_MODS` input mode.
+
+```c
+glfwSetInputMode(window, GLFW_LOCK_KEY_MODS, GLFW_TRUE);
+```
+
+When this input mode is enabled, any callback that receives
+[modifier bits](@ref mods) will have the @ref GLFW_MOD_CAPS_LOCK bit set if Caps
+Lock was on when the event occurred and the @ref GLFW_MOD_NUM_LOCK bit set if
+Num Lock was on.
+
+The `GLFW_KEY_LAST` constant holds the highest value of any
+[key token](@ref keys).
+
+
+### Text input {#input_char}
+
+GLFW supports text input in the form of a stream of
+[Unicode code points](https://en.wikipedia.org/wiki/Unicode), as produced by the
+operating system text input system.  Unlike key input, text input is affected by
+keyboard layouts and modifier keys and supports composing characters using
+[dead keys](https://en.wikipedia.org/wiki/Dead_key).  Once received, you can
+encode the code points into UTF-8 or any other encoding you prefer.
+
+Because an `unsigned int` is 32 bits long on all platforms supported by GLFW,
+you can treat the code point argument as native endian UTF-32.
+
+If you wish to offer regular text input, set a character callback.
+
+```c
+glfwSetCharCallback(window, character_callback);
+```
+
+The callback function receives Unicode code points for key events that would
+have led to regular text input and generally behaves as a standard text field on
+that platform.
+
+```c
+void character_callback(GLFWwindow* window, unsigned int codepoint)
+{
+}
+```
+
+
+### Key names {#input_key_name}
+
+If you wish to refer to keys by name, you can query the keyboard layout
+dependent name of printable keys with @ref glfwGetKeyName.
+
+```c
+const char* key_name = glfwGetKeyName(GLFW_KEY_W, 0);
+show_tutorial_hint("Press %s to move forward", key_name);
+```
+
+This function can handle both [keys and scancodes](@ref input_key).  If the
+specified key is `GLFW_KEY_UNKNOWN` then the scancode is used, otherwise it is
+ignored.  This matches the behavior of the key callback, meaning the callback
+arguments can always be passed unmodified to this function.
+
+
+## Mouse input {#input_mouse}
+
+Mouse input comes in many forms, including mouse motion, button presses and
+scrolling offsets.  The cursor appearance can also be changed, either to
+a custom image or a standard cursor shape from the system theme.
+
+
+### Cursor position {#cursor_pos}
+
+If you wish to be notified when the cursor moves over the window, set a cursor
+position callback.
+
+```c
+glfwSetCursorPosCallback(window, cursor_position_callback);
+```
+
+The callback functions receives the cursor position, measured in screen
+coordinates but relative to the top-left corner of the window content area.  On
+platforms that provide it, the full sub-pixel cursor position is passed on.
+
+```c
+static void cursor_position_callback(GLFWwindow* window, double xpos, double ypos)
+{
+}
+```
+
+The cursor position is also saved per-window and can be polled with @ref
+glfwGetCursorPos.
+
+```c
+double xpos, ypos;
+glfwGetCursorPos(window, &xpos, &ypos);
+```
+
+
+### Cursor mode {#cursor_mode}
+
+@anchor GLFW_CURSOR
+The `GLFW_CURSOR` input mode provides several cursor modes for special forms of
+mouse motion input.  By default, the cursor mode is `GLFW_CURSOR_NORMAL`,
+meaning the regular arrow cursor (or another cursor set with @ref glfwSetCursor)
+is used and cursor motion is not limited.
+
+If you wish to implement mouse motion based camera controls or other input
+schemes that require unlimited mouse movement, set the cursor mode to
+`GLFW_CURSOR_DISABLED`.
+
+```c
+glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_DISABLED);
+```
+
+This will hide the cursor and lock it to the specified window.  GLFW will then
+take care of all the details of cursor re-centering and offset calculation and
+providing the application with a virtual cursor position.  This virtual position
+is provided normally via both the cursor position callback and through polling.
+
+@note You should not implement your own version of this functionality using
+other features of GLFW.  It is not supported and will not work as robustly as
+`GLFW_CURSOR_DISABLED`.
+
+If you only wish the cursor to become hidden when it is over a window but still
+want it to behave normally, set the cursor mode to `GLFW_CURSOR_HIDDEN`.
+
+```c
+glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_HIDDEN);
+```
+
+This mode puts no limit on the motion of the cursor.
+
+If you wish the cursor to be visible but confined to the content area of the
+window, set the cursor mode to `GLFW_CURSOR_CAPTURED`.
+
+```c
+glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_CAPTURED);
+```
+
+The cursor will behave normally inside the content area but will not be able to
+leave unless the window loses focus.
+
+To exit out of either of these special modes, restore the `GLFW_CURSOR_NORMAL`
+cursor mode.
+
+```c
+glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_NORMAL);
+```
+
+If the cursor was disabled, this will move it back to its last visible position.
+
+
+@anchor GLFW_RAW_MOUSE_MOTION
+### Raw mouse motion {#raw_mouse_motion}
+
+When the cursor is disabled, raw (unscaled and unaccelerated) mouse motion can
+be enabled if available.
+
+Raw mouse motion is closer to the actual motion of the mouse across a surface.
+It is not affected by the scaling and acceleration applied to the motion of the
+desktop cursor.  That processing is suitable for a cursor while raw motion is
+better for controlling for example a 3D camera.  Because of this, raw mouse
+motion is only provided when the cursor is disabled.
+
+Call @ref glfwRawMouseMotionSupported to check if the current machine provides
+raw motion and set the `GLFW_RAW_MOUSE_MOTION` input mode to enable it.  It is
+disabled by default.
+
+```c
+if (glfwRawMouseMotionSupported())
+    glfwSetInputMode(window, GLFW_RAW_MOUSE_MOTION, GLFW_TRUE);
+```
+
+If supported, raw mouse motion can be enabled or disabled per-window and at any
+time but it will only be provided when the cursor is disabled.
+
+
+### Cursor objects {#cursor_object}
+
+GLFW supports creating both custom and system theme cursor images, encapsulated
+as @ref GLFWcursor objects.  They are created with @ref glfwCreateCursor or @ref
+glfwCreateStandardCursor and destroyed with @ref glfwDestroyCursor, or @ref
+glfwTerminate, if any remain.
+
+
+#### Custom cursor creation {#cursor_custom}
+
+A custom cursor is created with @ref glfwCreateCursor, which returns a handle to
+the created cursor object.  For example, this creates a 16x16 white square
+cursor with the hot-spot in the upper-left corner:
+
+```c
+unsigned char pixels[16 * 16 * 4];
+memset(pixels, 0xff, sizeof(pixels));
+
+GLFWimage image;
+image.width = 16;
+image.height = 16;
+image.pixels = pixels;
+
+GLFWcursor* cursor = glfwCreateCursor(&image, 0, 0);
+```
+
+If cursor creation fails, `NULL` will be returned, so it is necessary to check
+the return value.
+
+The image data is 32-bit, little-endian, non-premultiplied RGBA, i.e. eight bits
+per channel with the red channel first.  The pixels are arranged canonically as
+sequential rows, starting from the top-left corner.
+
+
+#### Standard cursor creation {#cursor_standard}
+
+A cursor with a [standard shape](@ref shapes) from the current system cursor
+theme can be created with @ref glfwCreateStandardCursor.
+
+```c
+GLFWcursor* url_cursor = glfwCreateStandardCursor(GLFW_POINTING_HAND_CURSOR);
+```
+
+These cursor objects behave in the exact same way as those created with @ref
+glfwCreateCursor except that the system cursor theme provides the actual image.
+
+A few of these shapes are not available everywhere.  If a shape is unavailable,
+`NULL` is returned.  See @ref glfwCreateStandardCursor for details.
+
+
+#### Cursor destruction {#cursor_destruction}
+
+When a cursor is no longer needed, destroy it with @ref glfwDestroyCursor.
+
+```c
+glfwDestroyCursor(cursor);
+```
+
+Cursor destruction always succeeds.  If the cursor is current for any window,
+that window will revert to the default cursor.  This does not affect the cursor
+mode.  All remaining cursors are destroyed when @ref glfwTerminate is called.
+
+
+#### Cursor setting {#cursor_set}
+
+A cursor can be set as current for a window with @ref glfwSetCursor.
+
+```c
+glfwSetCursor(window, cursor);
+```
+
+Once set, the cursor image will be used as long as the system cursor is over the
+content area of the window and the [cursor mode](@ref cursor_mode) is set
+to `GLFW_CURSOR_NORMAL`.
+
+A single cursor may be set for any number of windows.
+
+To revert to the default cursor, set the cursor of that window to `NULL`.
+
+```c
+glfwSetCursor(window, NULL);
+```
+
+When a cursor is destroyed, any window that has it set will revert to the
+default cursor.  This does not affect the cursor mode.
+
+
+### Cursor enter/leave events {#cursor_enter}
+
+If you wish to be notified when the cursor enters or leaves the content area of
+a window, set a cursor enter/leave callback.
+
+```c
+glfwSetCursorEnterCallback(window, cursor_enter_callback);
+```
+
+The callback function receives the new classification of the cursor.
+
+```c
+void cursor_enter_callback(GLFWwindow* window, int entered)
+{
+    if (entered)
+    {
+        // The cursor entered the content area of the window
+    }
+    else
+    {
+        // The cursor left the content area of the window
+    }
+}
+```
+
+You can query whether the cursor is currently inside the content area of the
+window with the [GLFW_HOVERED](@ref GLFW_HOVERED_attrib) window attribute.
+
+```c
+if (glfwGetWindowAttrib(window, GLFW_HOVERED))
+{
+    highlight_interface();
+}
+```
+
+
+### Mouse button input {#input_mouse_button}
+
+If you wish to be notified when a mouse button is pressed or released, set
+a mouse button callback.
+
+```c
+glfwSetMouseButtonCallback(window, mouse_button_callback);
+```
+
+The callback function receives the [mouse button](@ref buttons), button action
+and [modifier bits](@ref mods).
+
+```c
+void mouse_button_callback(GLFWwindow* window, int button, int action, int mods)
+{
+    if (button == GLFW_MOUSE_BUTTON_RIGHT && action == GLFW_PRESS)
+        popup_menu();
+}
+```
+
+The action is one of `GLFW_PRESS` or `GLFW_RELEASE`.
+
+The last reported state for every [supported mouse button](@ref buttons) is also
+saved in per-window state arrays that can be polled with @ref
+glfwGetMouseButton.
+
+```c
+int state = glfwGetMouseButton(window, GLFW_MOUSE_BUTTON_LEFT);
+if (state == GLFW_PRESS)
+{
+    upgrade_cow();
+}
+```
+
+The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`.
+
+This function only returns cached mouse button event state.  It does not poll
+the system for the current state of the mouse button.
+
+@anchor GLFW_STICKY_MOUSE_BUTTONS
+Whenever you poll state, you risk missing the state change you are looking for.
+If a pressed mouse button is released again before you poll its state, you will have
+missed the button press.  The recommended solution for this is to use a
+mouse button callback, but there is also the `GLFW_STICKY_MOUSE_BUTTONS`
+input mode.
+
+```c
+glfwSetInputMode(window, GLFW_STICKY_MOUSE_BUTTONS, GLFW_TRUE);
+```
+
+When sticky mouse buttons mode is enabled, the pollable state of a mouse button
+will remain `GLFW_PRESS` until the state of that button is polled with @ref
+glfwGetMouseButton.  Once it has been polled, if a mouse button release event
+had been processed in the meantime, the state will reset to `GLFW_RELEASE`,
+otherwise it will remain `GLFW_PRESS`.
+
+The `GLFW_MOUSE_BUTTON_LAST` constant holds the highest value of any
+[supported mouse button](@ref buttons).
+
+
+### Scroll input {#scrolling}
+
+If you wish to be notified when the user scrolls, whether with a mouse wheel or
+touchpad gesture, set a scroll callback.
+
+```c
+glfwSetScrollCallback(window, scroll_callback);
+```
+
+The callback function receives two-dimensional scroll offsets.
+
+```c
+void scroll_callback(GLFWwindow* window, double xoffset, double yoffset)
+{
+}
+```
+
+A normal mouse wheel, being vertical, provides offsets along the Y-axis.
+
+
+## Joystick input {#joystick}
+
+The joystick functions expose connected joysticks and controllers, with both
+referred to as joysticks.  It supports up to sixteen joysticks, ranging from
+`GLFW_JOYSTICK_1`, `GLFW_JOYSTICK_2` up to and including `GLFW_JOYSTICK_16` or
+`GLFW_JOYSTICK_LAST`.  You can test whether a [joystick](@ref joysticks) is
+present with @ref glfwJoystickPresent.
+
+```c
+int present = glfwJoystickPresent(GLFW_JOYSTICK_1);
+```
+
+Each joystick has zero or more axes, zero or more buttons, zero or more hats,
+a human-readable name, a user pointer and an SDL compatible GUID.
+
+Detected joysticks are added to the beginning of the array.  Once a joystick is
+detected, it keeps its assigned ID until it is disconnected or the library is
+terminated, so as joysticks are connected and disconnected, there may appear
+gaps in the IDs.
+
+Joystick axis, button and hat state is updated when polled and does not require
+a window to be created or events to be processed.  However, if you want joystick
+connection and disconnection events reliably delivered to the
+[joystick callback](@ref joystick_event) then you must
+[process events](@ref events).
+
+To see all the properties of all connected joysticks in real-time, run the
+`joysticks` test program.
+
+
+### Joystick axis states {#joystick_axis}
+
+The positions of all axes of a joystick are returned by @ref
+glfwGetJoystickAxes.  See the reference documentation for the lifetime of the
+returned array.
+
+```c
+int count;
+const float* axes = glfwGetJoystickAxes(GLFW_JOYSTICK_5, &count);
+```
+
+Each element in the returned array is a value between -1.0 and 1.0.
+
+
+### Joystick button states {#joystick_button}
+
+The states of all buttons of a joystick are returned by @ref
+glfwGetJoystickButtons.  See the reference documentation for the lifetime of the
+returned array.
+
+```c
+int count;
+const unsigned char* buttons = glfwGetJoystickButtons(GLFW_JOYSTICK_3, &count);
+```
+
+Each element in the returned array is either `GLFW_PRESS` or `GLFW_RELEASE`.
+
+For backward compatibility with earlier versions that did not have @ref
+glfwGetJoystickHats, the button array by default also includes all hats.  See
+the reference documentation for @ref glfwGetJoystickButtons for details.
+
+
+### Joystick hat states {#joystick_hat}
+
+The states of all hats are returned by @ref glfwGetJoystickHats.  See the
+reference documentation for the lifetime of the returned array.
+
+```c
+int count;
+const unsigned char* hats = glfwGetJoystickHats(GLFW_JOYSTICK_7, &count);
+```
+
+Each element in the returned array is one of the following:
+
+Name                  | Value
+----                  | -----
+`GLFW_HAT_CENTERED`   | 0
+`GLFW_HAT_UP`         | 1
+`GLFW_HAT_RIGHT`      | 2
+`GLFW_HAT_DOWN`       | 4
+`GLFW_HAT_LEFT`       | 8
+`GLFW_HAT_RIGHT_UP`   | `GLFW_HAT_RIGHT` \| `GLFW_HAT_UP`
+`GLFW_HAT_RIGHT_DOWN` | `GLFW_HAT_RIGHT` \| `GLFW_HAT_DOWN`
+`GLFW_HAT_LEFT_UP`    | `GLFW_HAT_LEFT` \| `GLFW_HAT_UP`
+`GLFW_HAT_LEFT_DOWN`  | `GLFW_HAT_LEFT` \| `GLFW_HAT_DOWN`
+
+The diagonal directions are bitwise combinations of the primary (up, right, down
+and left) directions and you can test for these individually by ANDing it with
+the corresponding direction.
+
+```c
+if (hats[2] & GLFW_HAT_RIGHT)
+{
+    // State of hat 2 could be right-up, right or right-down
+}
+```
+
+For backward compatibility with earlier versions that did not have @ref
+glfwGetJoystickHats, all hats are by default also included in the button array.
+See the reference documentation for @ref glfwGetJoystickButtons for details.
+
+
+### Joystick name {#joystick_name}
+
+The human-readable, UTF-8 encoded name of a joystick is returned by @ref
+glfwGetJoystickName.  See the reference documentation for the lifetime of the
+returned string.
+
+```c
+const char* name = glfwGetJoystickName(GLFW_JOYSTICK_4);
+```
+
+Joystick names are not guaranteed to be unique.  Two joysticks of the same model
+and make may have the same name.  Only the [joystick ID](@ref joysticks) is
+guaranteed to be unique, and only until that joystick is disconnected.
+
+
+### Joystick user pointer {#joystick_userptr}
+
+Each joystick has a user pointer that can be set with @ref
+glfwSetJoystickUserPointer and queried with @ref glfwGetJoystickUserPointer.
+This can be used for any purpose you need and will not be modified by GLFW.  The
+value will be kept until the joystick is disconnected or until the library is
+terminated.
+
+The initial value of the pointer is `NULL`.
+
+
+### Joystick configuration changes {#joystick_event}
+
+If you wish to be notified when a joystick is connected or disconnected, set
+a joystick callback.
+
+```c
+glfwSetJoystickCallback(joystick_callback);
+```
+
+The callback function receives the ID of the joystick that has been connected
+and disconnected and the event that occurred.
+
+```c
+void joystick_callback(int jid, int event)
+{
+    if (event == GLFW_CONNECTED)
+    {
+        // The joystick was connected
+    }
+    else if (event == GLFW_DISCONNECTED)
+    {
+        // The joystick was disconnected
+    }
+}
+```
+
+For joystick connection and disconnection events to be delivered on all
+platforms, you need to call one of the [event processing](@ref events)
+functions.  Joystick disconnection may also be detected and the callback
+called by joystick functions.  The function will then return whatever it
+returns for a disconnected joystick.
+
+Only @ref glfwGetJoystickName and @ref glfwGetJoystickUserPointer will return
+useful values for a disconnected joystick and only before the monitor callback
+returns.
+
+
+### Gamepad input {#gamepad}
+
+The joystick functions provide unlabeled axes, buttons and hats, with no
+indication of where they are located on the device.  Their order may also vary
+between platforms even with the same device.
+
+To solve this problem the SDL community crowdsourced the
+[SDL_GameControllerDB][] project, a database of mappings from many different
+devices to an Xbox-like gamepad.
+
+[SDL_GameControllerDB]: https://github.com/gabomdq/SDL_GameControllerDB
+
+GLFW supports this mapping format and contains a copy of the mappings
+available at the time of release.  See @ref gamepad_mapping for how to update
+this at runtime.  Mappings will be assigned to joysticks automatically any time
+a joystick is connected or the mappings are updated.
+
+You can check whether a joystick is both present and has a gamepad mapping with
+@ref glfwJoystickIsGamepad.
+
+```c
+if (glfwJoystickIsGamepad(GLFW_JOYSTICK_2))
+{
+    // Use as gamepad
+}
+```
+
+If you are only interested in gamepad input you can use this function instead of
+@ref glfwJoystickPresent.
+
+You can query the human-readable name provided by the gamepad mapping with @ref
+glfwGetGamepadName.  This may or may not be the same as the
+[joystick name](@ref joystick_name).
+
+```c
+const char* name = glfwGetGamepadName(GLFW_JOYSTICK_7);
+```
+
+To retrieve the gamepad state of a joystick, call @ref glfwGetGamepadState.
+
+```c
+GLFWgamepadstate state;
+
+if (glfwGetGamepadState(GLFW_JOYSTICK_3, &state))
+{
+    if (state.buttons[GLFW_GAMEPAD_BUTTON_A])
+    {
+        input_jump();
+    }
+
+    input_speed(state.axes[GLFW_GAMEPAD_AXIS_RIGHT_TRIGGER]);
+}
+```
+
+The @ref GLFWgamepadstate struct has two arrays; one for button states and one
+for axis states.  The values for each button and axis are the same as for the
+@ref glfwGetJoystickButtons and @ref glfwGetJoystickAxes functions, i.e.
+`GLFW_PRESS` or `GLFW_RELEASE` for buttons and -1.0 to 1.0 inclusive for axes.
+
+The sizes of the arrays and the positions within each array are fixed.
+
+The [button indices](@ref gamepad_buttons) are `GLFW_GAMEPAD_BUTTON_A`,
+`GLFW_GAMEPAD_BUTTON_B`, `GLFW_GAMEPAD_BUTTON_X`, `GLFW_GAMEPAD_BUTTON_Y`,
+`GLFW_GAMEPAD_BUTTON_LEFT_BUMPER`, `GLFW_GAMEPAD_BUTTON_RIGHT_BUMPER`,
+`GLFW_GAMEPAD_BUTTON_BACK`, `GLFW_GAMEPAD_BUTTON_START`,
+`GLFW_GAMEPAD_BUTTON_GUIDE`, `GLFW_GAMEPAD_BUTTON_LEFT_THUMB`,
+`GLFW_GAMEPAD_BUTTON_RIGHT_THUMB`, `GLFW_GAMEPAD_BUTTON_DPAD_UP`,
+`GLFW_GAMEPAD_BUTTON_DPAD_RIGHT`, `GLFW_GAMEPAD_BUTTON_DPAD_DOWN` and
+`GLFW_GAMEPAD_BUTTON_DPAD_LEFT`.
+
+For those who prefer, there are also the `GLFW_GAMEPAD_BUTTON_CROSS`,
+`GLFW_GAMEPAD_BUTTON_CIRCLE`, `GLFW_GAMEPAD_BUTTON_SQUARE` and
+`GLFW_GAMEPAD_BUTTON_TRIANGLE` aliases for the A, B, X and Y button indices.
+
+The [axis indices](@ref gamepad_axes) are `GLFW_GAMEPAD_AXIS_LEFT_X`,
+`GLFW_GAMEPAD_AXIS_LEFT_Y`, `GLFW_GAMEPAD_AXIS_RIGHT_X`,
+`GLFW_GAMEPAD_AXIS_RIGHT_Y`, `GLFW_GAMEPAD_AXIS_LEFT_TRIGGER` and
+`GLFW_GAMEPAD_AXIS_RIGHT_TRIGGER`.
+
+The `GLFW_GAMEPAD_BUTTON_LAST` and `GLFW_GAMEPAD_AXIS_LAST` constants equal
+the largest available index for each array.
+
+
+### Gamepad mappings {#gamepad_mapping}
+
+GLFW contains a copy of the mappings available in [SDL_GameControllerDB][] at
+the time of release.  Newer ones can be added at runtime with @ref
+glfwUpdateGamepadMappings.
+
+```c
+const char* mappings = load_file_contents("game/data/gamecontrollerdb.txt");
+
+glfwUpdateGamepadMappings(mappings);
+```
+
+This function supports everything from single lines up to and including the
+unmodified contents of the whole `gamecontrollerdb.txt` file.
+
+If you are compiling GLFW from source with CMake you can update the built-in mappings by
+building the _update_mappings_ target.  This runs the `GenerateMappings.cmake` CMake
+script, which downloads `gamecontrollerdb.txt` and regenerates the `mappings.h` header
+file.
+
+Below is a description of the mapping format.  Please keep in mind that __this
+description is not authoritative__.  The format is defined by the SDL and
+SDL_GameControllerDB projects and their documentation and code takes precedence.
+
+Each mapping is a single line of comma-separated values describing the GUID,
+name and layout of the gamepad.  Lines that do not begin with a hexadecimal
+digit are ignored.
+
+The first value is always the gamepad GUID, a 32 character long hexadecimal
+string that typically identifies its make, model, revision and the type of
+connection to the computer.  When this information is not available, the GUID is
+generated using the gamepad name.  GLFW uses the SDL 2.0.5+ GUID format but can
+convert from the older formats.
+
+The second value is always the human-readable name of the gamepad.
+
+All subsequent values are in the form `<field>:<value>` and describe the layout
+of the mapping.  These fields may not all be present and may occur in any order.
+
+The button fields are `a`, `b`, `x`, `y`, `back`, `start`, `guide`, `dpup`,
+`dpright`, `dpdown`, `dpleft`, `leftshoulder`, `rightshoulder`, `leftstick` and
+`rightstick`.
+
+The axis fields are `leftx`, `lefty`, `rightx`, `righty`, `lefttrigger` and
+`righttrigger`.
+
+The value of an axis or button field can be a joystick button, a joystick axis,
+a hat bitmask or empty.  Joystick buttons are specified as `bN`, for example
+`b2` for the third button.  Joystick axes are specified as `aN`, for example
+`a7` for the eighth button.  Joystick hat bit masks are specified as `hN.N`, for
+example `h0.8` for left on the first hat.  More than one bit may be set in the
+mask.
+
+Before an axis there may be a `+` or `-` range modifier, for example `+a3` for
+the positive half of the fourth axis.  This restricts input to only the positive
+or negative halves of the joystick axis.  After an axis or half-axis there may
+be the `~` inversion modifier, for example `a2~` or `-a7~`.  This negates the
+values of the gamepad axis.
+
+The hat bit mask match the [hat states](@ref hat_state) in the joystick
+functions.
+
+There is also the special `platform` field that specifies which platform the
+mapping is valid for.  Possible values are `Windows`, `Mac OS X` and `Linux`.
+
+Below is an example of what a gamepad mapping might look like.  It is the
+one built into GLFW for Xbox controllers accessed via the XInput API on Windows.
+This example has been broken into several lines to fit on the page, but real
+gamepad mappings must be a single line.
+
+```
+78696e70757401000000000000000000,XInput Gamepad (GLFW),platform:Windows,a:b0,
+b:b1,x:b2,y:b3,leftshoulder:b4,rightshoulder:b5,back:b6,start:b7,leftstick:b8,
+rightstick:b9,leftx:a0,lefty:a1,rightx:a2,righty:a3,lefttrigger:a4,
+righttrigger:a5,dpup:h0.1,dpright:h0.2,dpdown:h0.4,dpleft:h0.8,
+```
+
+@note GLFW does not yet support the output range and modifiers `+` and `-` that
+were recently added to SDL.  The input modifiers `+`, `-` and `~` are supported
+and described above.
+
+
+## Time input {#time}
+
+GLFW provides high-resolution time input, in seconds, with @ref glfwGetTime.
+
+```c
+double seconds = glfwGetTime();
+```
+
+It returns the number of seconds since the library was initialized with @ref
+glfwInit.  The platform-specific time sources used typically have micro- or
+nanosecond resolution.
+
+You can modify the base time with @ref glfwSetTime.
+
+```c
+glfwSetTime(4.0);
+```
+
+This sets the time to the specified time, in seconds, and it continues to count
+from there.
+
+You can also access the raw timer used to implement the functions above,
+with @ref glfwGetTimerValue.
+
+```c
+uint64_t value = glfwGetTimerValue();
+```
+
+This value is in 1&nbsp;/&nbsp;frequency seconds.  The frequency of the raw
+timer varies depending on the operating system and hardware.  You can query the
+frequency, in Hz, with @ref glfwGetTimerFrequency.
+
+```c
+uint64_t frequency = glfwGetTimerFrequency();
+```
+
+
+## Clipboard input and output {#clipboard}
+
+If the system clipboard contains a UTF-8 encoded string or if it can be
+converted to one, you can retrieve it with @ref glfwGetClipboardString.  See the
+reference documentation for the lifetime of the returned string.
+
+```c
+const char* text = glfwGetClipboardString(NULL);
+if (text)
+{
+    insert_text(text);
+}
+```
+
+If the clipboard is empty or if its contents could not be converted, `NULL` is
+returned.
+
+The contents of the system clipboard can be set to a UTF-8 encoded string with
+@ref glfwSetClipboardString.
+
+```c
+glfwSetClipboardString(NULL, "A string with words in it");
+```
+
+
+## Path drop input {#path_drop}
+
+If you wish to receive the paths of files and/or directories dropped on
+a window, set a file drop callback.
+
+```c
+glfwSetDropCallback(window, drop_callback);
+```
+
+The callback function receives an array of paths encoded as UTF-8.
+
+```c
+void drop_callback(GLFWwindow* window, int count, const char** paths)
+{
+    int i;
+    for (i = 0;  i < count;  i++)
+        handle_dropped_file(paths[i]);
+}
+```
+
+The path array and its strings are only valid until the file drop callback
+returns, as they may have been generated specifically for that event.  You need
+to make a deep copy of the array if you want to keep the paths.

+# Internal structure {#internals_guide}
+
+[TOC]
+
+There are several interfaces inside GLFW.  Each interface has its own area of
+responsibility and its own naming conventions.
+
+
+## Public interface {#internals_public}
+
+The most well-known is the public interface, described in the glfw3.h header
+file.  This is implemented in source files shared by all platforms and these
+files contain no platform-specific code.  This code usually ends up calling the
+platform and internal interfaces to do the actual work.
+
+The public interface uses the OpenGL naming conventions except with GLFW and
+glfw instead of GL and gl.  For struct members, where OpenGL sets no precedent,
+it use headless camel case.
+
+Examples: `glfwCreateWindow`, `GLFWwindow`, `GLFW_RED_BITS`
+
+
+## Native interface {#internals_native}
+
+The [native interface](@ref native) is a small set of publicly available
+but platform-specific functions, described in the glfw3native.h header file and
+used to gain access to the underlying window, context and (on some platforms)
+display handles used by the platform interface.
+
+The function names of the native interface are similar to those of the public
+interface, but embeds the name of the interface that the returned handle is
+from.
+
+Examples: `glfwGetX11Window`, `glfwGetWGLContext`
+
+
+## Internal interface {#internals_internal}
+
+The internal interface consists of utility functions used by all other
+interfaces.  It is shared code implemented in the same shared source files as
+the public and event interfaces.  The internal interface is described in the
+internal.h header file.
+
+The internal interface is in charge of GLFW's global data, which it stores in
+a `_GLFWlibrary` struct named `_glfw`.
+
+The internal interface uses the same style as the public interface, except all
+global names have a leading underscore.
+
+Examples: `_glfwIsValidContextConfig`, `_GLFWwindow`, `_glfw.monitorCount`
+
+
+## Platform interface {#internals_platform}
+
+The platform interface implements all platform-specific operations as a service
+to the public interface.  This includes event processing.  The platform
+interface is never directly called by application code and never directly calls
+application-provided callbacks.  It is also prohibited from modifying the
+platform-independent part of the internal structs.  Instead, it calls the event
+interface when events interesting to GLFW are received.
+
+The platform interface mostly mirrors those parts of the public interface that needs to
+perform platform-specific operations on some or all platforms.
+
+The window system bits of the platform API is called through the `_GLFWplatform` struct of
+function pointers, to allow runtime selection of platform.  This includes the window and
+context creation, input and event processing, monitor and Vulkan surface creation parts of
+GLFW.  This is located in the global `_glfw` struct.
+
+Examples: `_glfw.platform.createWindow`
+
+The timer, threading and module loading bits of the platform API are plain functions with
+a `_glfwPlatform` prefix, as these things are independent of what window system is being
+used.
+
+Examples: `_glfwPlatformGetTimerValue`
+
+The platform interface also defines structs that contain platform-specific
+global and per-object state.  Their names mirror those of the internal
+interface, except that an interface-specific suffix is added.
+
+Examples: `_GLFWwindowX11`, `_GLFWcontextWGL`
+
+These structs are incorporated as members into the internal interface structs
+using special macros that name them after the specific interface used.  This
+prevents shared code from accidentally using these members.
+
+Examples: `window->win32.handle`, `_glfw.x11.display`
+
+
+## Event interface {#internals_event}
+
+The event interface is implemented in the same shared source files as the public
+interface and is responsible for delivering the events it receives to the
+application, either via callbacks, via window state changes or both.
+
+The function names of the event interface use a `_glfwInput` prefix and the
+ObjectEvent pattern.
+
+Examples: `_glfwInputWindowFocus`, `_glfwInputCursorPos`
+
+
+## Static functions {#internals_static}
+
+Static functions may be used by any interface and have no prefixes or suffixes.
+These use headless camel case.
+
+Examples: `isValidElementForJoystick`
+
+
+## Configuration macros {#internals_config}
+
+GLFW uses a number of configuration macros to select at compile time which
+interfaces and code paths to use.  They are defined in the GLFW CMake target.
+
+Configuration macros the same style as tokens in the public interface, except
+with a leading underscore.
+
+Examples: `_GLFW_WIN32`, `_GLFW_BUILD_DLL`

+# Introduction to the API {#intro_guide}
+
+[TOC]
+
+This guide introduces the basic concepts of GLFW and describes initialization,
+error handling and API guarantees and limitations.  For a broad but shallow
+tutorial, see @ref quick_guide instead.  For details on a specific function in
+this category, see the @ref init.
+
+There are also guides for the other areas of GLFW.
+
+ - @ref window_guide
+ - @ref context_guide
+ - @ref vulkan_guide
+ - @ref monitor_guide
+ - @ref input_guide
+
+
+## Initialization and termination {#intro_init}
+
+Before most GLFW functions may be called, the library must be initialized.
+This initialization checks what features are available on the machine,
+enumerates monitors, initializes the timer and performs any required
+platform-specific initialization.
+
+Only the following functions may be called before the library has been
+successfully initialized, and only from the main thread.
+
+ - @ref glfwGetVersion
+ - @ref glfwGetVersionString
+ - @ref glfwPlatformSupported
+ - @ref glfwGetError
+ - @ref glfwSetErrorCallback
+ - @ref glfwInitHint
+ - @ref glfwInitAllocator
+ - @ref glfwInitVulkanLoader
+ - @ref glfwInit
+ - @ref glfwTerminate
+
+Calling any other function before successful initialization will cause a @ref
+GLFW_NOT_INITIALIZED error.
+
+
+### Initializing GLFW {#intro_init_init}
+
+The library is initialized with @ref glfwInit, which returns `GLFW_FALSE` if an
+error occurred.
+
+```c
+if (!glfwInit())
+{
+    // Handle initialization failure
+}
+```
+
+If any part of initialization fails, any parts that succeeded are terminated as
+if @ref glfwTerminate had been called.  The library only needs to be initialized
+once and additional calls to an already initialized library will return
+`GLFW_TRUE` immediately.
+
+Once the library has been successfully initialized, it should be terminated
+before the application exits.  Modern systems are very good at freeing resources
+allocated by programs that exit, but GLFW sometimes has to change global system
+settings and these might not be restored without termination.
+
+@macos When the library is initialized the main menu and dock icon are created.
+These are not desirable for a command-line only program.  The creation of the
+main menu and dock icon can be disabled with the @ref GLFW_COCOA_MENUBAR init
+hint.
+
+
+### Initialization hints {#init_hints}
+
+Initialization hints are set before @ref glfwInit and affect how the library
+behaves until termination.  Hints are set with @ref glfwInitHint.
+
+```c
+glfwInitHint(GLFW_JOYSTICK_HAT_BUTTONS, GLFW_FALSE);
+```
+
+The values you set hints to are never reset by GLFW, but they only take effect
+during initialization.  Once GLFW has been initialized, any values you set will
+be ignored until the library is terminated and initialized again.
+
+Some hints are platform specific.  These may be set on any platform but they
+will only affect their specific platform.  Other platforms will ignore them.
+Setting these hints requires no platform specific headers or functions.
+
+
+#### Shared init hints {#init_hints_shared}
+
+@anchor GLFW_PLATFORM
+__GLFW_PLATFORM__ specifies the platform to use for windowing and input.
+Possible values are `GLFW_ANY_PLATFORM`, `GLFW_PLATFORM_WIN32`,
+`GLFW_PLATFORM_COCOA`, `GLFW_PLATFORM_WAYLAND`, `GLFW_PLATFORM_X11` and
+`GLFW_PLATFORM_NULL`.  The default value is `GLFW_ANY_PLATFORM`, which will
+choose any platform the library includes support for except for the Null
+backend.
+
+
+@anchor GLFW_JOYSTICK_HAT_BUTTONS
+__GLFW_JOYSTICK_HAT_BUTTONS__ specifies whether to also expose joystick hats as
+buttons, for compatibility with earlier versions of GLFW that did not have @ref
+glfwGetJoystickHats.  Possible values are `GLFW_TRUE` and `GLFW_FALSE`.
+
+@anchor GLFW_ANGLE_PLATFORM_TYPE_hint
+__GLFW_ANGLE_PLATFORM_TYPE__ specifies the platform type (rendering backend) to
+request when using OpenGL ES and EGL via [ANGLE][].  If the requested platform
+type is unavailable, ANGLE will use its default. Possible values are one of
+`GLFW_ANGLE_PLATFORM_TYPE_NONE`, `GLFW_ANGLE_PLATFORM_TYPE_OPENGL`,
+`GLFW_ANGLE_PLATFORM_TYPE_OPENGLES`, `GLFW_ANGLE_PLATFORM_TYPE_D3D9`,
+`GLFW_ANGLE_PLATFORM_TYPE_D3D11`, `GLFW_ANGLE_PLATFORM_TYPE_VULKAN` and
+`GLFW_ANGLE_PLATFORM_TYPE_METAL`.
+
+[ANGLE]: https://chromium.googlesource.com/angle/angle/
+
+The ANGLE platform type is specified via the `EGL_ANGLE_platform_angle`
+extension.  This extension is not used if this hint is
+`GLFW_ANGLE_PLATFORM_TYPE_NONE`, which is the default value.
+
+
+#### macOS specific init hints {#init_hints_osx}
+
+@anchor GLFW_COCOA_CHDIR_RESOURCES_hint
+__GLFW_COCOA_CHDIR_RESOURCES__ specifies whether to set the current directory to
+the application to the `Contents/Resources` subdirectory of the application's
+bundle, if present.  Possible values are `GLFW_TRUE` and `GLFW_FALSE`.  This is
+ignored on other platforms.
+
+@anchor GLFW_COCOA_MENUBAR_hint
+__GLFW_COCOA_MENUBAR__ specifies whether to create the menu bar and dock icon
+when GLFW is initialized.  This applies whether the menu bar is created from
+a nib or manually by GLFW.  Possible values are `GLFW_TRUE` and `GLFW_FALSE`.
+This is ignored on other platforms.
+
+
+#### Wayland specific init hints {#init_hints_wayland}
+
+@anchor GLFW_WAYLAND_LIBDECOR_hint
+__GLFW_WAYLAND_LIBDECOR__ specifies whether to use [libdecor][] for window
+decorations where available.  Possible values are `GLFW_WAYLAND_PREFER_LIBDECOR`
+and `GLFW_WAYLAND_DISABLE_LIBDECOR`.  This is ignored on other platforms.
+
+[libdecor]: https://gitlab.freedesktop.org/libdecor/libdecor
+
+
+#### X11 specific init hints {#init_hints_x11}
+
+@anchor GLFW_X11_XCB_VULKAN_SURFACE_hint
+__GLFW_X11_XCB_VULKAN_SURFACE__ specifies whether to prefer the
+`VK_KHR_xcb_surface` extension for creating Vulkan surfaces, or whether to use
+the `VK_KHR_xlib_surface` extension.  Possible values are `GLFW_TRUE` and
+`GLFW_FALSE`.  This is ignored on other platforms.
+
+
+#### Supported and default values {#init_hints_values}
+
+Initialization hint              | Default value                   | Supported values
+-------------------------------- | ------------------------------- | ----------------
+@ref GLFW_PLATFORM               | `GLFW_ANY_PLATFORM`             | `GLFW_ANY_PLATFORM`, `GLFW_PLATFORM_WIN32`, `GLFW_PLATFORM_COCOA`, `GLFW_PLATFORM_WAYLAND`, `GLFW_PLATFORM_X11` or `GLFW_PLATFORM_NULL`
+@ref GLFW_JOYSTICK_HAT_BUTTONS   | `GLFW_TRUE`                     | `GLFW_TRUE` or `GLFW_FALSE`
+@ref GLFW_ANGLE_PLATFORM_TYPE    | `GLFW_ANGLE_PLATFORM_TYPE_NONE` | `GLFW_ANGLE_PLATFORM_TYPE_NONE`, `GLFW_ANGLE_PLATFORM_TYPE_OPENGL`, `GLFW_ANGLE_PLATFORM_TYPE_OPENGLES`, `GLFW_ANGLE_PLATFORM_TYPE_D3D9`, `GLFW_ANGLE_PLATFORM_TYPE_D3D11`, `GLFW_ANGLE_PLATFORM_TYPE_VULKAN` or `GLFW_ANGLE_PLATFORM_TYPE_METAL`
+@ref GLFW_COCOA_CHDIR_RESOURCES  | `GLFW_TRUE`                     | `GLFW_TRUE` or `GLFW_FALSE`
+@ref GLFW_COCOA_MENUBAR          | `GLFW_TRUE`                     | `GLFW_TRUE` or `GLFW_FALSE`
+@ref GLFW_WAYLAND_LIBDECOR       | `GLFW_WAYLAND_PREFER_LIBDECOR`  | `GLFW_WAYLAND_PREFER_LIBDECOR` or `GLFW_WAYLAND_DISABLE_LIBDECOR`
+@ref GLFW_X11_XCB_VULKAN_SURFACE | `GLFW_TRUE`                     | `GLFW_TRUE` or `GLFW_FALSE`
+
+
+### Runtime platform selection {#platform}
+
+GLFW can be compiled for more than one platform (window system) at once.  This lets
+a single library binary support both Wayland and X11 on Linux and other Unix-like systems.
+
+You can control platform selection via the @ref GLFW_PLATFORM initialization hint.  By
+default, this is set to @ref GLFW_ANY_PLATFORM, which will look for supported window
+systems in order of priority and select the first one it finds.  It can also be set to any
+specific platform to have GLFW only look for that one.
+
+```c
+glfwInitHint(GLFW_PLATFORM, GLFW_PLATFORM_X11);
+```
+
+This mechanism also provides the Null platform, which is always supported but needs to be
+explicitly requested.  This platform is effectively a stub, emulating a window system on
+a single 1080p monitor, but will not interact with any actual window system.
+
+```c
+glfwInitHint(GLFW_PLATFORM, GLFW_PLATFORM_NULL);
+```
+
+You can test whether a library binary was compiled with support for a specific platform
+with @ref glfwPlatformSupported.
+
+```c
+if (glfwPlatformSupported(GLFW_PLATFORM_WAYLAND))
+    glfwInitHint(GLFW_PLATFORM, GLFW_PLATFORM_WAYLAND);
+```
+
+Once GLFW has been initialized, you can query which platform was selected with @ref
+glfwGetPlatform.
+
+```c
+int platform = glfwGetPlatform();
+```
+
+If you are using any [native access functions](@ref native), especially on Linux and other
+Unix-like systems, then you may need to check that you are calling the ones matching the
+selected platform.
+
+
+### Custom heap memory allocator {#init_allocator}
+
+The heap memory allocator can be customized before initialization with @ref
+glfwInitAllocator.
+
+```c
+GLFWallocator allocator;
+allocator.allocate = my_malloc;
+allocator.reallocate = my_realloc;
+allocator.deallocate = my_free;
+allocator.user = NULL;
+
+glfwInitAllocator(&allocator);
+```
+
+The allocator will be made active at the beginning of initialization and will be used by
+GLFW until the library has been fully terminated.  Any allocator set after initialization
+will be picked up only at the next initialization.
+
+The allocator will only be used for allocations that would have been made with
+the C standard library.  Memory allocations that must be made with platform
+specific APIs will still use those.
+
+The allocation function must have a signature matching @ref GLFWallocatefun.  It receives
+the desired size, in bytes, and the user pointer passed to @ref glfwInitAllocator and
+returns the address to the allocated memory block.
+
+```c
+void* my_malloc(size_t size, void* user)
+{
+    ...
+}
+```
+
+The documentation for @ref GLFWallocatefun also lists the requirements and limitations for
+an allocation function.  If the active one does not meet all of these, GLFW may fail.
+
+The reallocation function must have a function signature matching @ref GLFWreallocatefun.
+It receives the memory block to be reallocated, the new desired size, in bytes, and the user
+pointer passed to @ref glfwInitAllocator and returns the address to the resized memory
+block.
+
+```c
+void* my_realloc(void* block, size_t size, void* user)
+{
+    ...
+}
+```
+
+The documentation for @ref GLFWreallocatefun also lists the requirements and limitations
+for a reallocation function.  If the active one does not meet all of these, GLFW may fail.
+
+The deallocation function must have a function signature matching @ref GLFWdeallocatefun.
+It receives the memory block to be deallocated and the user pointer passed to @ref
+glfwInitAllocator.
+
+```c
+void my_free(void* block, void* user)
+{
+    ...
+}
+```
+
+The documentation for @ref GLFWdeallocatefun also lists the requirements and limitations
+for a deallocation function.  If the active one does not meet all of these, GLFW may fail.
+
+
+### Terminating GLFW {#intro_init_terminate}
+
+Before your application exits, you should terminate the GLFW library if it has
+been initialized.  This is done with @ref glfwTerminate.
+
+```c
+glfwTerminate();
+```
+
+This will destroy any remaining window, monitor and cursor objects, restore any
+modified gamma ramps, re-enable the screensaver if it had been disabled and free
+any other resources allocated by GLFW.
+
+Once the library is terminated, it is as if it had never been initialized, therefore
+you will need to initialize it again before being able to use GLFW.  If the
+library was not initialized or had already been terminated, it returns
+immediately.
+
+
+## Error handling {#error_handling}
+
+Some GLFW functions have return values that indicate an error, but this is often
+not very helpful when trying to figure out what happened or why it occurred.
+Other functions have no return value reserved for errors, so error notification
+needs a separate channel.  Finally, far from all GLFW functions have return
+values.
+
+The last [error code](@ref errors) for the calling thread can be queried at any
+time with @ref glfwGetError.
+
+```c
+int code = glfwGetError(NULL);
+
+if (code != GLFW_NO_ERROR)
+    handle_error(code);
+```
+
+If no error has occurred since the last call, @ref GLFW_NO_ERROR (zero) is
+returned.  The error is cleared before the function returns.
+
+The error code indicates the general category of the error.  Some error codes,
+such as @ref GLFW_NOT_INITIALIZED has only a single meaning, whereas others like
+@ref GLFW_PLATFORM_ERROR are used for many different errors.
+
+GLFW often has more information about an error than its general category.  You
+can retrieve a UTF-8 encoded human-readable description along with the error
+code.  If no error has occurred since the last call, the description is set to
+`NULL`.
+
+```c
+const char* description;
+int code = glfwGetError(&description);
+
+if (description)
+    display_error_message(code, description);
+```
+
+The retrieved description string is only valid until the next error occurs.
+This means you must make a copy of it if you want to keep it.
+
+You can also set an error callback, which will be called each time an error
+occurs.  It is set with @ref glfwSetErrorCallback.
+
+```c
+glfwSetErrorCallback(error_callback);
+```
+
+The error callback receives the same error code and human-readable description
+returned by @ref glfwGetError.
+
+```c
+void error_callback(int code, const char* description)
+{
+    display_error_message(code, description);
+}
+```
+
+The error callback is called after the error is stored, so calling @ref
+glfwGetError from within the error callback returns the same values as the
+callback argument.
+
+The description string passed to the callback is only valid until the error
+callback returns.  This means you must make a copy of it if you want to keep it.
+
+__Reported errors are never fatal.__  As long as GLFW was successfully
+initialized, it will remain initialized and in a safe state until terminated
+regardless of how many errors occur.  If an error occurs during initialization
+that causes @ref glfwInit to fail, any part of the library that was initialized
+will be safely terminated.
+
+Do not rely on a currently invalid call to generate a specific error, as in the
+future that same call may generate a different error or become valid.
+
+
+## Coordinate systems {#coordinate_systems}
+
+GLFW has two primary coordinate systems: the _virtual screen_ and the window
+_content area_ or _content area_.  Both use the same unit: _virtual screen
+coordinates_, or just _screen coordinates_, which don't necessarily correspond
+to pixels.
+
+<img src="spaces.svg" width="90%" />
+
+Both the virtual screen and the content area coordinate systems have the X-axis
+pointing to the right and the Y-axis pointing down.
+
+Window and monitor positions are specified as the position of the upper-left
+corners of their content areas relative to the virtual screen, while cursor
+positions are specified relative to a window's content area.
+
+Because the origin of the window's content area coordinate system is also the
+point from which the window position is specified, you can translate content
+area coordinates to the virtual screen by adding the window position.  The
+window frame, when present, extends out from the content area but does not
+affect the window position.
+
+Almost all positions and sizes in GLFW are measured in screen coordinates
+relative to one of the two origins above.  This includes cursor positions,
+window positions and sizes, window frame sizes, monitor positions and video mode
+resolutions.
+
+Two exceptions are the [monitor physical size](@ref monitor_size), which is
+measured in millimetres, and [framebuffer size](@ref window_fbsize), which is
+measured in pixels.
+
+Pixels and screen coordinates may map 1:1 on your machine, but they won't on
+every other machine, for example on a Mac with a Retina display.  The ratio
+between screen coordinates and pixels may also change at run-time depending on
+which monitor the window is currently considered to be on.
+
+
+## Guarantees and limitations {#guarantees_limitations}
+
+This section describes the conditions under which GLFW can be expected to
+function, barring bugs in the operating system or drivers.  Use of GLFW outside
+these limits may work on some platforms, or on some machines, or some of the
+time, or on some versions of GLFW, but it may break at any time and this will
+not be considered a bug.
+
+
+### Pointer lifetimes {#lifetime}
+
+GLFW will never free any pointer you provide to it, and you must never free any
+pointer it provides to you.
+
+Many GLFW functions return pointers to dynamically allocated structures, strings
+or arrays, and some callbacks are provided with strings or arrays.  These are
+always managed by GLFW and should never be freed by the application.  The
+lifetime of these pointers is documented for each GLFW function and callback.
+If you need to keep this data, you must copy it before its lifetime expires.
+
+Many GLFW functions accept pointers to structures or strings allocated by the
+application.  These are never freed by GLFW and are always the responsibility of
+the application.  If GLFW needs to keep the data in these structures or strings,
+it is copied before the function returns.
+
+Pointer lifetimes are guaranteed not to be shortened in future minor or patch
+releases.
+
+
+### Reentrancy {#reentrancy}
+
+GLFW event processing and object destruction are not reentrant.  This means that
+the following functions must not be called from any callback function:
+
+ - @ref glfwDestroyWindow
+ - @ref glfwDestroyCursor
+ - @ref glfwPollEvents
+ - @ref glfwWaitEvents
+ - @ref glfwWaitEventsTimeout
+ - @ref glfwTerminate
+
+These functions may be made reentrant in future minor or patch releases, but
+functions not on this list will not be made non-reentrant.
+
+
+### Thread safety {#thread_safety}
+
+Most GLFW functions must only be called from the main thread (the thread that
+calls main), but some may be called from any thread once the library has been
+initialized.  Before initialization the whole library is thread-unsafe.
+
+The reference documentation for every GLFW function states whether it is limited
+to the main thread.
+
+Initialization, termination, event processing and the creation and
+destruction of windows, cursors and OpenGL and OpenGL ES contexts are all
+restricted to the main thread due to limitations of one or several platforms.
+
+Because event processing must be performed on the main thread, all callbacks
+except for the error callback will only be called on that thread.  The error
+callback may be called on any thread, as any GLFW function may generate errors.
+
+The error code and description may be queried from any thread.
+
+ - @ref glfwGetError
+
+Empty events may be posted from any thread.
+
+ - @ref glfwPostEmptyEvent
+
+The window user pointer and close flag may be read and written from any thread,
+but this is not synchronized by GLFW.
+
+ - @ref glfwGetWindowUserPointer
+ - @ref glfwSetWindowUserPointer
+ - @ref glfwWindowShouldClose
+ - @ref glfwSetWindowShouldClose
+
+These functions for working with OpenGL and OpenGL ES contexts may be called
+from any thread, but the window object is not synchronized by GLFW.
+
+ - @ref glfwMakeContextCurrent
+ - @ref glfwGetCurrentContext
+ - @ref glfwSwapBuffers
+ - @ref glfwSwapInterval
+ - @ref glfwExtensionSupported
+ - @ref glfwGetProcAddress
+
+The raw timer functions may be called from any thread.
+
+ - @ref glfwGetTimerFrequency
+ - @ref glfwGetTimerValue
+
+The regular timer may be used from any thread, but reading and writing the timer
+offset is not synchronized by GLFW.
+
+ - @ref glfwGetTime
+ - @ref glfwSetTime
+
+Library version information may be queried from any thread.
+
+ - @ref glfwGetVersion
+ - @ref glfwGetVersionString
+
+Platform information may be queried from any thread.
+
+ - @ref glfwPlatformSupported
+ - @ref glfwGetPlatform
+
+All Vulkan related functions may be called from any thread.
+
+ - @ref glfwVulkanSupported
+ - @ref glfwGetRequiredInstanceExtensions
+ - @ref glfwGetInstanceProcAddress
+ - @ref glfwGetPhysicalDevicePresentationSupport
+ - @ref glfwCreateWindowSurface
+
+GLFW uses synchronization objects internally only to manage the per-thread
+context and error states.  Additional synchronization is left to the
+application.
+
+Functions that may currently be called from any thread will always remain so,
+but functions that are currently limited to the main thread may be updated to
+allow calls from any thread in future releases.
+
+
+### Version compatibility {#compatibility}
+
+GLFW uses [Semantic Versioning](https://semver.org/).  This guarantees source
+and binary backward compatibility with earlier minor versions of the API.  This
+means that you can drop in a newer version of the library and existing programs
+will continue to compile and existing binaries will continue to run.
+
+Once a function or constant has been added, the signature of that function or
+value of that constant will remain unchanged until the next major version of
+GLFW.  No compatibility of any kind is guaranteed between major versions.
+
+Undocumented behavior, i.e. behavior that is not described in the documentation,
+may change at any time until it is documented.
+
+If the reference documentation and the implementation differ, the reference
+documentation will almost always take precedence and the implementation will be
+fixed in the next release.  The reference documentation will also take
+precedence over anything stated in a guide.
+
+
+### Event order {#event_order}
+
+The order of arrival of related events is not guaranteed to be consistent
+across platforms.  The exception is synthetic key and mouse button release
+events, which are always delivered after the window defocus event.
+
+
+## Version management {#intro_version}
+
+GLFW provides mechanisms for identifying what version of GLFW your application
+was compiled against as well as what version it is currently running against.
+If you are loading GLFW dynamically (not just linking dynamically), you can use
+this to verify that the library binary is compatible with your application.
+
+
+### Compile-time version {#intro_version_compile}
+
+The compile-time version of GLFW is provided by the GLFW header with the
+`GLFW_VERSION_MAJOR`, `GLFW_VERSION_MINOR` and `GLFW_VERSION_REVISION` macros.
+
+```c
+printf("Compiled against GLFW %i.%i.%i\n",
+       GLFW_VERSION_MAJOR,
+       GLFW_VERSION_MINOR,
+       GLFW_VERSION_REVISION);
+```
+
+
+### Run-time version {#intro_version_runtime}
+
+The run-time version can be retrieved with @ref glfwGetVersion, a function that
+may be called regardless of whether GLFW is initialized.
+
+```c
+int major, minor, revision;
+glfwGetVersion(&major, &minor, &revision);
+
+printf("Running against GLFW %i.%i.%i\n", major, minor, revision);
+```
+
+
+### Version string {#intro_version_string}
+
+GLFW 3 also provides a compile-time generated version string that describes the
+version, platform, compiler and any platform-specific compile-time options.
+This is primarily intended for submitting bug reports, to allow developers to
+see which code paths are enabled in a binary.
+
+The version string is returned by @ref glfwGetVersionString, a function that may
+be called regardless of whether GLFW is initialized.
+
+__Do not use the version string__ to parse the GLFW library version.  The @ref
+glfwGetVersion function already provides the version of the running library
+binary.
+
+__Do not use the version string__ to parse what platforms are supported.  The @ref
+glfwPlatformSupported function lets you query platform support.
+
+__GLFW 3.4:__ The format of this string was changed to support the addition of
+[runtime platform selection](@ref platform).
+
+The format of the string is as follows:
+ - The version of GLFW
+ - For each supported platform:
+   - The name of the window system API
+   - The name of the window system specific context creation API, if applicable
+ - The names of the always supported context creation APIs EGL and OSMesa
+ - Any additional compile-time options, APIs and (on Windows) what compiler was used
+
+For example, compiling GLFW 3.4 with MinGW as a DLL for Windows, may result in a version string
+like this:
+
+```c
+3.4.0 Win32 WGL Null EGL OSMesa MinGW DLL
+```
+
+Compiling GLFW as a static library for Linux, with both Wayland and X11 enabled, may
+result in a version string like this:
+
+```c
+3.4.0 Wayland X11 GLX Null EGL OSMesa monotonic
+```

+# Introduction {#mainpage}
+
+GLFW is a free, Open Source, multi-platform library for OpenGL, OpenGL ES and
+Vulkan application development.  It provides a simple, platform-independent API
+for creating windows, contexts and surfaces, reading input, handling events, etc.
+
+@ref news list new features, caveats and deprecations.
+
+@ref quick_guide is a guide for users new to GLFW.  It takes you through how to
+write a small but complete program.
+
+There are guides for each section of the API:
+
+ - @ref intro_guide – initialization, error handling and high-level design
+ - @ref window_guide – creating and working with windows and framebuffers
+ - @ref context_guide – working with OpenGL and OpenGL ES contexts
+ - @ref vulkan_guide - working with Vulkan objects and extensions
+ - @ref monitor_guide – enumerating and working with monitors and video modes
+ - @ref input_guide – receiving events, polling and processing input
+
+Once you have written a program, see @ref compile_guide and @ref build_guide.
+
+The [reference documentation](modules.html) provides more detailed information
+about specific functions.
+
+@ref moving_guide explains what has changed and how to update existing code to
+use the new API.
+
+There is a section on @ref guarantees_limitations for pointer lifetimes,
+reentrancy, thread safety, event order and backward and forward compatibility.

+# Monitor guide {#monitor_guide}
+
+[TOC]
+
+This guide introduces the monitor related functions of GLFW.  For details on
+a specific function in this category, see the @ref monitor.  There are also
+guides for the other areas of GLFW.
+
+ - @ref intro_guide
+ - @ref window_guide
+ - @ref context_guide
+ - @ref vulkan_guide
+ - @ref input_guide
+
+
+## Monitor objects {#monitor_object}
+
+A monitor object represents a currently connected monitor and is represented as
+a pointer to the [opaque](https://en.wikipedia.org/wiki/Opaque_data_type) type
+@ref GLFWmonitor.  Monitor objects cannot be created or destroyed by the
+application and retain their addresses until the monitors they represent are
+disconnected or until the library is [terminated](@ref intro_init_terminate).
+
+Each monitor has a current video mode, a list of supported video modes,
+a virtual position, a human-readable name, an estimated physical size and
+a gamma ramp.  One of the monitors is the primary monitor.
+
+The virtual position of a monitor is in
+[screen coordinates](@ref coordinate_systems) and, together with the current
+video mode, describes the viewports that the connected monitors provide into the
+virtual desktop that spans them.
+
+To see how GLFW views your monitor setup and its available video modes, run the
+`monitors` test program.
+
+
+### Retrieving monitors {#monitor_monitors}
+
+The primary monitor is returned by @ref glfwGetPrimaryMonitor.  It is the user's
+preferred monitor and is usually the one with global UI elements like task bar
+or menu bar.
+
+```c
+GLFWmonitor* primary = glfwGetPrimaryMonitor();
+```
+
+You can retrieve all currently connected monitors with @ref glfwGetMonitors.
+See the reference documentation for the lifetime of the returned array.
+
+```c
+int count;
+GLFWmonitor** monitors = glfwGetMonitors(&count);
+```
+
+The primary monitor is always the first monitor in the returned array, but other
+monitors may be moved to a different index when a monitor is connected or
+disconnected.
+
+
+### Monitor configuration changes {#monitor_event}
+
+If you wish to be notified when a monitor is connected or disconnected, set
+a monitor callback.
+
+```c
+glfwSetMonitorCallback(monitor_callback);
+```
+
+The callback function receives the handle for the monitor that has been
+connected or disconnected and the event that occurred.
+
+```c
+void monitor_callback(GLFWmonitor* monitor, int event)
+{
+    if (event == GLFW_CONNECTED)
+    {
+        // The monitor was connected
+    }
+    else if (event == GLFW_DISCONNECTED)
+    {
+        // The monitor was disconnected
+    }
+}
+```
+
+If a monitor is disconnected, all windows that are full screen on it will be
+switched to windowed mode before the callback is called.  Only @ref
+glfwGetMonitorName and @ref glfwGetMonitorUserPointer will return useful values
+for a disconnected monitor and only before the monitor callback returns.
+
+
+## Monitor properties {#monitor_properties}
+
+Each monitor has a current video mode, a list of supported video modes,
+a virtual position, a content scale, a human-readable name, a user pointer, an
+estimated physical size and a gamma ramp.
+
+
+### Video modes {#monitor_modes}
+
+GLFW generally does a good job selecting a suitable video mode when you create
+a full screen window, change its video mode or make a windowed one full
+screen, but it is sometimes useful to know exactly which video modes are
+supported.
+
+Video modes are represented as @ref GLFWvidmode structures.  You can get an
+array of the video modes supported by a monitor with @ref glfwGetVideoModes.
+See the reference documentation for the lifetime of the returned array.
+
+```c
+int count;
+GLFWvidmode* modes = glfwGetVideoModes(monitor, &count);
+```
+
+To get the current video mode of a monitor call @ref glfwGetVideoMode.  See the
+reference documentation for the lifetime of the returned pointer.
+
+```c
+const GLFWvidmode* mode = glfwGetVideoMode(monitor);
+```
+
+The resolution of a video mode is specified in
+[screen coordinates](@ref coordinate_systems), not pixels.
+
+
+### Physical size {#monitor_size}
+
+The physical size of a monitor in millimetres, or an estimation of it, can be
+retrieved with @ref glfwGetMonitorPhysicalSize.  This has no relation to its
+current _resolution_, i.e. the width and height of its current
+[video mode](@ref monitor_modes).
+
+```c
+int width_mm, height_mm;
+glfwGetMonitorPhysicalSize(monitor, &width_mm, &height_mm);
+```
+
+While this can be used to calculate the raw DPI of a monitor, this is often not
+useful.  Instead, use the [monitor content scale](@ref monitor_scale) and
+[window content scale](@ref window_scale) to scale your content.
+
+
+### Content scale {#monitor_scale}
+
+The content scale for a monitor can be retrieved with @ref
+glfwGetMonitorContentScale.
+
+```c
+float xscale, yscale;
+glfwGetMonitorContentScale(monitor, &xscale, &yscale);
+```
+
+For more information on what the content scale is and how to use it, see
+[window content scale](@ref window_scale).
+
+
+### Virtual position {#monitor_pos}
+
+The position of the monitor on the virtual desktop, in
+[screen coordinates](@ref coordinate_systems), can be retrieved with @ref
+glfwGetMonitorPos.
+
+```c
+int xpos, ypos;
+glfwGetMonitorPos(monitor, &xpos, &ypos);
+```
+
+
+### Work area {#monitor_workarea}
+
+The area of a monitor not occupied by global task bars or menu bars is the work
+area.  This is specified in [screen coordinates](@ref coordinate_systems) and
+can be retrieved with @ref glfwGetMonitorWorkarea.
+
+```c
+int xpos, ypos, width, height;
+glfwGetMonitorWorkarea(monitor, &xpos, &ypos, &width, &height);
+```
+
+
+### Human-readable name {#monitor_name}
+
+The human-readable, UTF-8 encoded name of a monitor is returned by @ref
+glfwGetMonitorName.  See the reference documentation for the lifetime of the
+returned string.
+
+```c
+const char* name = glfwGetMonitorName(monitor);
+```
+
+Monitor names are not guaranteed to be unique.  Two monitors of the same model
+and make may have the same name.  Only the monitor handle is guaranteed to be
+unique, and only until that monitor is disconnected.
+
+
+### User pointer {#monitor_userptr}
+
+Each monitor has a user pointer that can be set with @ref
+glfwSetMonitorUserPointer and queried with @ref glfwGetMonitorUserPointer.  This
+can be used for any purpose you need and will not be modified by GLFW.  The
+value will be kept until the monitor is disconnected or until the library is
+terminated.
+
+The initial value of the pointer is `NULL`.
+
+
+### Gamma ramp {#monitor_gamma}
+
+The gamma ramp of a monitor can be set with @ref glfwSetGammaRamp, which accepts
+a monitor handle and a pointer to a @ref GLFWgammaramp structure.
+
+```c
+GLFWgammaramp ramp;
+unsigned short red[256], green[256], blue[256];
+
+ramp.size = 256;
+ramp.red = red;
+ramp.green = green;
+ramp.blue = blue;
+
+for (i = 0;  i < ramp.size;  i++)
+{
+    // Fill out gamma ramp arrays as desired
+}
+
+glfwSetGammaRamp(monitor, &ramp);
+```
+
+The gamma ramp data is copied before the function returns, so there is no need
+to keep it around once the ramp has been set.
+
+It is recommended that your gamma ramp have the same size as the current gamma
+ramp for that monitor.
+
+The current gamma ramp for a monitor is returned by @ref glfwGetGammaRamp.  See
+the reference documentation for the lifetime of the returned structure.
+
+```c
+const GLFWgammaramp* ramp = glfwGetGammaRamp(monitor);
+```
+
+If you wish to set a regular gamma ramp, you can have GLFW calculate it for you
+from the desired exponent with @ref glfwSetGamma, which in turn calls @ref
+glfwSetGammaRamp with the resulting ramp.
+
+```c
+glfwSetGamma(monitor, 1.0);
+```
+
+To experiment with gamma correction via the @ref glfwSetGamma function, run the
+`gamma` test program.
+
+@note The software controlled gamma ramp is applied _in addition_ to the
+hardware gamma correction, which today is typically an approximation of sRGB
+gamma.  This means that setting a perfectly linear ramp, or gamma 1.0, will
+produce the default (usually sRGB-like) behavior.

+# Moving from GLFW 2 to 3 {#moving_guide}
+
+[TOC]
+
+This is a transition guide for moving from GLFW 2 to 3.  It describes what has
+changed or been removed, but does _not_ include
+[new features](@ref news) unless they are required when moving an existing code
+base onto the new API.  For example, the new multi-monitor functions are
+required to create full screen windows with GLFW 3.
+
+
+## Changed and removed features {#moving_removed}
+
+### Renamed library and header file {#moving_renamed_files}
+
+The GLFW 3 header is named @ref glfw3.h and moved to the `GLFW` directory, to
+avoid collisions with the headers of other major versions.  Similarly, the GLFW
+3 library is named `glfw3,` except when it's installed as a shared library on
+Unix-like systems, where it uses the [soname][] `libglfw.so.3`.
+
+[soname]: https://en.wikipedia.org/wiki/soname
+
+__Old syntax__
+```c
+#include <GL/glfw.h>
+```
+
+__New syntax__
+```c
+#include <GLFW/glfw3.h>
+```
+
+
+### Removal of threading functions {#moving_threads}
+
+The threading functions have been removed, including the per-thread sleep
+function.  They were fairly primitive, under-used, poorly integrated and took
+time away from the focus of GLFW (i.e.  context, input and window).  There are
+better threading libraries available and native threading support is available
+in both [C++11][] and [C11][], both of which are gaining traction.
+
+[C++11]: https://en.cppreference.com/w/cpp/thread
+[C11]: https://en.cppreference.com/w/c/thread
+
+If you wish to use the C++11 or C11 facilities but your compiler doesn't yet
+support them, see the [TinyThread++][] and [TinyCThread][] projects created by
+the original author of GLFW.  These libraries implement a usable subset of the
+threading APIs in C++11 and C11, and in fact some GLFW 3 test programs use
+TinyCThread.
+
+[TinyThread++]: https://gitorious.org/tinythread/tinythreadpp
+[TinyCThread]: https://github.com/tinycthread/tinycthread
+
+However, GLFW 3 has better support for _use from multiple threads_ than GLFW
+2 had.  Contexts can be made current on any thread, although only a single
+thread at a time, and the documentation explicitly states which functions may be
+used from any thread and which must only be used from the main thread.
+
+__Removed functions__
+> `glfwSleep`, `glfwCreateThread`, `glfwDestroyThread`, `glfwWaitThread`,
+> `glfwGetThreadID`, `glfwCreateMutex`, `glfwDestroyMutex`, `glfwLockMutex`,
+> `glfwUnlockMutex`, `glfwCreateCond`, `glfwDestroyCond`, `glfwWaitCond`,
+> `glfwSignalCond`, `glfwBroadcastCond` and `glfwGetNumberOfProcessors`.
+
+__Removed types__
+> `GLFWthreadfun`
+
+
+### Removal of image and texture loading {#moving_image}
+
+The image and texture loading functions have been removed.  They only supported
+the Targa image format, making them mostly useful for beginner level examples.
+To become of sufficiently high quality to warrant keeping them in GLFW 3, they
+would need not only to support other formats, but also modern extensions to
+OpenGL texturing.  This would either add a number of external
+dependencies (libjpeg, libpng, etc.), or force GLFW to ship with inline versions
+of these libraries.
+
+As there already are libraries doing this, it is unnecessary both to duplicate
+the work and to tie the duplicate to GLFW.  The resulting library would also be
+platform-independent, as both OpenGL and stdio are available wherever GLFW is.

+
+
+### Removal of GLFWCALL macro {#moving_stdcall}
+
+The `GLFWCALL` macro, which made callback functions use [\_\_stdcall][stdcall]
+on Windows, has been removed.  GLFW is written in C, not Pascal.  Removing this
+macro means there's one less thing for application programmers to remember, i.e.
+the requirement to mark all callback functions with `GLFWCALL`.  It also
+simplifies the creation of DLLs and DLL link libraries, as there's no need to
+explicitly disable `@n` entry point suffixes.
+
+[stdcall]: https://msdn.microsoft.com/en-us/library/zxk0tw93.aspx
+
+__Old syntax__
+```c
+void GLFWCALL callback_function(...);
+```
+
+__New syntax__
+```c
+void callback_function(...);
+```
+
+
+### Window handle parameters {#moving_window_handles}
+
+Because GLFW 3 supports multiple windows, window handle parameters have been
+added to all window-related GLFW functions and callbacks.  The handle of
+a newly created window is returned by @ref glfwCreateWindow (formerly
+`glfwOpenWindow`).  Window handles are pointers to the
+[opaque][opaque-type] type @ref GLFWwindow.
+
+[opaque-type]: https://en.wikipedia.org/wiki/Opaque_data_type
+
+__Old syntax__
+```c
+glfwSetWindowTitle("New Window Title");
+```
+
+__New syntax__
+```c
+glfwSetWindowTitle(window, "New Window Title");
+```
+
+
+### Explicit monitor selection {#moving_monitor}
+
+GLFW 3 provides support for multiple monitors.  To request a full screen mode window,
+instead of passing `GLFW_FULLSCREEN` you specify which monitor you wish the
+window to use.  The @ref glfwGetPrimaryMonitor function returns the monitor that
+GLFW 2 would have selected, but there are many other
+[monitor functions](@ref monitor_guide).  Monitor handles are pointers to the
+[opaque][opaque-type] type @ref GLFWmonitor.
+
+__Old basic full screen__
+```c
+glfwOpenWindow(640, 480, 8, 8, 8, 0, 24, 0, GLFW_FULLSCREEN);
+```
+
+__New basic full screen__
+```c
+window = glfwCreateWindow(640, 480, "My Window", glfwGetPrimaryMonitor(), NULL);
+```
+
+@note The framebuffer bit depth parameters of `glfwOpenWindow` have been turned
+into [window hints](@ref window_hints), but as they have been given
+[sane defaults](@ref window_hints_values) you rarely need to set these hints.
+
+
+### Removal of automatic event polling {#moving_autopoll}
+
+GLFW 3 does not automatically poll for events in @ref glfwSwapBuffers, meaning
+you need to call @ref glfwPollEvents or @ref glfwWaitEvents yourself.  Unlike
+buffer swap, which acts on a single window, the event processing functions act
+on all windows at once.
+
+__Old basic main loop__
+```c
+while (...)
+{
+    // Process input
+    // Render output
+    glfwSwapBuffers();
+}
+```
+
+__New basic main loop__
+```c
+while (...)
+{
+    // Process input
+    // Render output
+    glfwSwapBuffers(window);
+    glfwPollEvents();
+}
+```
+
+
+### Explicit context management {#moving_context}
+
+Each GLFW 3 window has its own OpenGL context and only you, the application
+programmer, can know which context should be current on which thread at any
+given time.  Therefore, GLFW 3 leaves that decision to you.
+
+This means that you need to call @ref glfwMakeContextCurrent after creating
+a window before you can call any OpenGL functions.
+
+
+### Separation of window and framebuffer sizes {#moving_hidpi}
+
+Window positions and sizes now use screen coordinates, which may not be the same
+as pixels on machines with high-DPI monitors.  This is important as OpenGL uses
+pixels, not screen coordinates.  For example, the rectangle specified with
+`glViewport` needs to use pixels.  Therefore, framebuffer size functions have
+been added.  You can retrieve the size of the framebuffer of a window with @ref
+glfwGetFramebufferSize function.  A framebuffer size callback has also been
+added, which can be set with @ref glfwSetFramebufferSizeCallback.
+
+__Old basic viewport setup__
+```c
+glfwGetWindowSize(&width, &height);
+glViewport(0, 0, width, height);
+```
+
+__New basic viewport setup__
+```c
+glfwGetFramebufferSize(window, &width, &height);
+glViewport(0, 0, width, height);
+```
+
+
+### Window closing changes {#moving_window_close}
+
+The `GLFW_OPENED` window parameter has been removed.  As long as the window has
+not been destroyed, whether through @ref glfwDestroyWindow or @ref
+glfwTerminate, the window is "open".
+
+A user attempting to close a window is now just an event like any other.  Unlike
+GLFW 2, windows and contexts created with GLFW 3 will never be destroyed unless
+you choose them to be.  Each window now has a close flag that is set to
+`GLFW_TRUE` when the user attempts to close that window.  By default, nothing else
+happens and the window stays visible.  It is then up to you to either destroy
+the window, take some other action or ignore the request.
+
+You can query the close flag at any time with @ref glfwWindowShouldClose and set
+it at any time with @ref glfwSetWindowShouldClose.
+
+__Old basic main loop__
+```c
+while (glfwGetWindowParam(GLFW_OPENED))
+{
+    ...
+}
+```
+
+__New basic main loop__
+```c
+while (!glfwWindowShouldClose(window))
+{
+    ...
+}
+```
+
+The close callback no longer returns a value.  Instead, it is called after the
+close flag has been set, so it can optionally override its value, before
+event processing completes.  You may however not call @ref glfwDestroyWindow
+from the close callback (or any other window related callback).
+
+__Old syntax__
+```c
+int GLFWCALL window_close_callback(void);
+```
+
+__New syntax__
+```c
+void window_close_callback(GLFWwindow* window);
+```
+
+@note GLFW never clears the close flag to `GLFW_FALSE`, meaning you can use it
+for other reasons to close the window as well, for example the user choosing
+Quit from an in-game menu.
+
+
+### Persistent window hints {#moving_hints}
+
+The `glfwOpenWindowHint` function has been renamed to @ref glfwWindowHint.
+
+Window hints are no longer reset to their default values on window creation, but
+instead retain their values until modified by @ref glfwWindowHint or @ref
+glfwDefaultWindowHints, or until the library is terminated and re-initialized.
+
+
+### Video mode enumeration {#moving_video_modes}
+
+Video mode enumeration is now per-monitor.  The @ref glfwGetVideoModes function
+now returns all available modes for a specific monitor instead of requiring you
+to guess how large an array you need.  The `glfwGetDesktopMode` function, which
+had poorly defined behavior, has been replaced by @ref glfwGetVideoMode, which
+returns the current mode of a monitor.
+
+
+### Removal of character actions {#moving_char_up}
+
+The action parameter of the [character callback](@ref GLFWcharfun) has been
+removed.  This was an artefact of the origin of GLFW, i.e. being developed in
+English by a Swede.  However, many keyboard layouts require more than one key to
+produce characters with diacritical marks. Even the Swedish keyboard layout
+requires this for uncommon cases like ü.
+
+__Old syntax__
+```c
+void GLFWCALL character_callback(int character, int action);
+```
+
+__New syntax__
+```c
+void character_callback(GLFWwindow* window, int character);
+```
+
+
+### Cursor position changes {#moving_cursorpos}
+
+The `glfwGetMousePos` function has been renamed to @ref glfwGetCursorPos,
+`glfwSetMousePos` to @ref glfwSetCursorPos and `glfwSetMousePosCallback` to @ref
+glfwSetCursorPosCallback.
+
+The cursor position is now `double` instead of `int`, both for the direct
+functions and for the callback.  Some platforms can provide sub-pixel cursor
+movement and this data is now passed on to the application where available.  On
+platforms where this is not provided, the decimal part is zero.
+
+GLFW 3 only allows you to position the cursor within a window using @ref
+glfwSetCursorPos (formerly `glfwSetMousePos`) when that window is active.
+Unless the window is active, the function fails silently.
+
+
+### Wheel position replaced by scroll offsets {#moving_wheel}
+
+The `glfwGetMouseWheel` function has been removed.  Scrolling is the input of
+offsets and has no absolute position.  The mouse wheel callback has been
+replaced by a [scroll callback](@ref GLFWscrollfun) that receives
+two-dimensional floating point scroll offsets.  This allows you to receive
+precise scroll data from for example modern touchpads.
+
+__Old syntax__
+```c
+void GLFWCALL mouse_wheel_callback(int position);
+```
+
+__New syntax__
+```c
+void scroll_callback(GLFWwindow* window, double xoffset, double yoffset);
+```
+
+__Removed functions__
+> `glfwGetMouseWheel`
+
+
+### Key repeat action {#moving_repeat}
+
+The `GLFW_KEY_REPEAT` enable has been removed and key repeat is always enabled
+for both keys and characters.  A new key action, `GLFW_REPEAT`, has been added
+to allow the [key callback](@ref GLFWkeyfun) to distinguish an initial key press
+from a repeat.  Note that @ref glfwGetKey still returns only `GLFW_PRESS` or
+`GLFW_RELEASE`.
+
+
+### Physical key input {#moving_keys}
+
+GLFW 3 key tokens map to physical keys, unlike in GLFW 2 where they mapped to
+the values generated by the current keyboard layout.  The tokens are named
+according to the values they would have in the standard US layout, but this
+is only a convenience, as most programmers are assumed to know that layout.
+This means that (for example) `GLFW_KEY_LEFT_BRACKET` is always a single key and
+is the same key in the same place regardless of what keyboard layouts the users
+of your program have.
+
+The key input facility was never meant for text input, although using it that
+way worked slightly better in GLFW 2.  If you were using it to input text, you
+should be using the character callback instead, on both GLFW 2 and 3.  This will
+give you the characters being input, as opposed to the keys being pressed.
+
+GLFW 3 has key tokens for all keys on a standard 105 key keyboard, so instead of
+having to remember whether to check for `a` or `A`, you now check for
+@ref GLFW_KEY_A.
+
+
+### Joystick function changes {#moving_joystick}
+
+The `glfwGetJoystickPos` function has been renamed to @ref glfwGetJoystickAxes.
+
+The `glfwGetJoystickParam` function and the `GLFW_PRESENT`, `GLFW_AXES` and
+`GLFW_BUTTONS` tokens have been replaced by the @ref glfwJoystickPresent
+function as well as axis and button counts returned by the @ref
+glfwGetJoystickAxes and @ref glfwGetJoystickButtons functions.
+
+
+### Win32 MBCS support {#moving_mbcs}
+
+The Win32 port of GLFW 3 will not compile in [MBCS mode][MBCS].  However,
+because the use of the Unicode version of the Win32 API doesn't affect the
+process as a whole, but only those windows created using it, it's perfectly
+possible to call MBCS functions from other parts of the same application.
+Therefore, even if an application using GLFW has MBCS mode code, there's no need
+for GLFW itself to support it.
+
+[MBCS]: https://msdn.microsoft.com/en-us/library/5z097dxa.aspx
+
+
+### Support for versions of Windows older than XP {#moving_windows}
+
+All explicit support for version of Windows older than XP has been removed.
+There is no code that actively prevents GLFW 3 from running on these earlier
+versions, but it uses Win32 functions that those versions lack.
+
+Windows XP was released in 2001, and by now (January 2015) it has not only
+replaced almost all earlier versions of Windows, but is itself rapidly being
+replaced by Windows 7 and 8.  The MSDN library doesn't even provide
+documentation for version older than Windows 2000, making it difficult to
+maintain compatibility with these versions even if it was deemed worth the
+effort.
+
+The Win32 API has also not stood still, and GLFW 3 uses many functions only
+present on Windows XP or later.  Even supporting an OS as new as XP (new
+from the perspective of GLFW 2, which still supports Windows 95) requires
+runtime checking for a number of functions that are present only on modern
+version of Windows.
+
+
+### Capture of system-wide hotkeys {#moving_syskeys}
+
+The ability to disable and capture system-wide hotkeys like Alt+Tab has been
+removed.  Modern applications, whether they're games, scientific visualisations
+or something else, are nowadays expected to be good desktop citizens and allow
+these hotkeys to function even when running in full screen mode.
+
+
+### Automatic termination {#moving_terminate}
+
+GLFW 3 does not register @ref glfwTerminate with `atexit` at initialization,
+because `exit` calls registered functions from the calling thread and while it
+is permitted to call `exit` from any thread, @ref glfwTerminate must only be
+called from the main thread.
+
+To release all resources allocated by GLFW, you should call @ref glfwTerminate
+yourself, from the main thread, before the program terminates.  Note that this
+destroys all windows not already destroyed with @ref glfwDestroyWindow,
+invalidating any window handles you may still have.
+
+
+### GLU header inclusion {#moving_glu}
+
+GLFW 3 does not by default include the GLU header and GLU itself has been
+deprecated by [Khronos][].  __New projects should not use GLU__, but if you need
+it for legacy code that has been moved to GLFW 3, you can request that the GLFW
+header includes it by defining @ref GLFW_INCLUDE_GLU before the inclusion of the
+GLFW header.
+
+[Khronos]: https://en.wikipedia.org/wiki/Khronos_Group
+
+__Old syntax__
+```c
+#include <GL/glfw.h>
+```
+
+__New syntax__
+```c
+#define GLFW_INCLUDE_GLU
+#include <GLFW/glfw3.h>
+```
+
+There are many libraries that offer replacements for the functionality offered
+by GLU.  For the matrix helper functions, see math libraries like [GLM][] (for
+C++), [linmath.h][] (for C) and others.  For the tessellation functions, see for
+example [libtess2][].

+# Release notes for version 3.4 {#news}
+
+[TOC]
+
+
+## New features {#features}
+
+### Runtime platform selection {#runtime_platform_selection}
+
+GLFW now supports being compiled for multiple backends and selecting between
+them at runtime with the @ref GLFW_PLATFORM init hint.  After initialization the
+selected platform can be queried with @ref glfwGetPlatform.  You can check if
+support for a given platform is compiled in with @ref glfwPlatformSupported.
+
+For more information see @ref platform.
+
+
+### More standard cursor shapes {#more_cursor_shapes}
+
+GLFW now provides the standard cursor shapes @ref GLFW_RESIZE_NWSE_CURSOR and
+@ref GLFW_RESIZE_NESW_CURSOR for diagonal resizing, @ref GLFW_RESIZE_ALL_CURSOR
+for omnidirectional resizing and @ref GLFW_NOT_ALLOWED_CURSOR for showing an
+action is not allowed.
+
+Unlike the original set, these shapes may not be available everywhere and
+creation will then fail with the new @ref GLFW_CURSOR_UNAVAILABLE error.
+
+The cursors for horizontal and vertical resizing are now referred to as @ref
+GLFW_RESIZE_EW_CURSOR and @ref GLFW_RESIZE_NS_CURSOR, and the pointing hand
+cursor is now referred to as @ref GLFW_POINTING_HAND_CURSOR.  The older names
+are still available.
+
+For more information see @ref cursor_standard.
+
+
+### Mouse event passthrough {#mouse_input_passthrough}
+
+GLFW now provides the [GLFW_MOUSE_PASSTHROUGH](@ref GLFW_MOUSE_PASSTHROUGH_hint)
+window hint for making a window transparent to mouse input, lettings events pass
+to whatever window is behind it.  This can also be changed after window
+creation with the matching [window attribute](@ref GLFW_MOUSE_PASSTHROUGH_attrib).
+
+
+### Ability to get window title {#window_title_function}
+
+GLFW now supports querying the title of a window with the @ref glfwGetWindowTitle
+function.
+
+For more information see @ref window_title.
+
+
+### Captured cursor mode {#captured_cursor_mode}
+
+GLFW now supports confining the cursor to the window content area with the @ref
+GLFW_CURSOR_CAPTURED cursor mode.
+
+For more information see @ref cursor_mode.
+
+
+### Support for custom heap memory allocator {#custom_heap_allocator}
+
+GLFW now supports plugging a custom heap memory allocator at initialization with
+@ref glfwInitAllocator.  The allocator is a struct of type @ref GLFWallocator
+with function pointers corresponding to the standard library functions `malloc`,
+`realloc` and `free`.
+
+For more information see @ref init_allocator.
+
+
+### Window hint for framebuffer scaling {#scale_framebuffer_hint}
+
+GLFW now allows provides the
+[GLFW_SCALE_FRAMEBUFFER](@ref GLFW_SCALE_FRAMEBUFFER_hint) window hint for
+controlling framebuffer scaling on platforms that handle scaling by keeping the
+window size the same while resizing the framebuffer.  The default value is to
+allow framebuffer scaling.
+
+This was already possible on macOS via the
+[GLFW_COCOA_RETINA_FRAMEBUFFER](@ref GLFW_COCOA_RETINA_FRAMEBUFFER_hint) window
+hint.  This is now another name for the same hint value.
+
+For more information see @ref window_scale.
+
+
+### Window hints for initial window position {#window_position_hint}
+
+GLFW now provides the @ref GLFW_POSITION_X and @ref GLFW_POSITION_Y window hints for
+specifying the initial position of the window.  This removes the need to create a hidden
+window, move it and then show it.  The default value of these hints is
+`GLFW_ANY_POSITION`, which selects the previous behavior.
+
+For more information see @ref window_pos.
+
+
+### ANGLE rendering backend hint {#angle_renderer_hint}
+
+GLFW now provides the
+[GLFW_ANGLE_PLATFORM_TYPE](@ref GLFW_ANGLE_PLATFORM_TYPE_hint) init hint for
+requesting a specific rendering backend when using [ANGLE][] to create OpenGL ES
+contexts.
+
+[ANGLE]: https://chromium.googlesource.com/angle/angle/
+
+
+### Windows window menu keyboard access hint {#win32_keymenu_hint}
+
+GLFW now provides the
+[GLFW_WIN32_KEYBOARD_MENU](@ref GLFW_WIN32_KEYBOARD_MENU_hint) window hint for
+enabling keyboard access to the window menu via the Alt+Space and
+Alt-and-then-Space shortcuts.  This may be useful for more GUI-oriented
+applications.
+
+
+### Windows STARTUPINFO show command hint {#win32_showdefault_hint}
+
+GLFW now provides the [GLFW_WIN32_SHOWDEFAULT](@ref GLFW_WIN32_SHOWDEFAULT_hint) window
+hint for applying the show command in the program's `STARTUPINFO` when showing the window
+for the first time.  This may be useful for the main window of a windowed-mode tool.
+
+
+### Cocoa NSView native access function {#cocoa_nsview_function}
+
+GLFW now provides the @ref glfwGetCocoaView native access function
+for returning the Cocoa NSView.
+
+
+### Wayland libdecor decorations {#wayland_libdecor_decorations}
+
+GLFW now supports improved client-side window decorations via
+[libdecor](https://gitlab.freedesktop.org/libdecor/libdecor).  This provides
+fully featured window decorations on desktop environments like GNOME.
+
+Support for libdecor can be toggled before GLFW is initialized with the
+[GLFW_WAYLAND_LIBDECOR](@ref GLFW_WAYLAND_LIBDECOR_hint) init hint.  It is
+enabled by default.
+
+This feature has also been available in GLFW 3.3 since 3.3.9.
+
+
+### Wayland surface app_id hint {#wayland_app_id_hint}
+
+GLFW now supports specifying the app_id for a Wayland window using the
+[GLFW_WAYLAND_APP_ID](@ref GLFW_WAYLAND_APP_ID_hint) window hint string.
+
+
+### X11 Vulkan window surface hint {#x11_xcb_vulkan_surface}
+
+GLFW now supports disabling the use of `VK_KHR_xcb_surface` over
+`VK_KHR_xlib_surface` where available, with the
+[GLFW_X11_XCB_VULKAN_SURFACE](@ref GLFW_X11_XCB_VULKAN_SURFACE_hint) init hint.
+This affects @ref glfwGetRequiredInstanceExtensions and @ref
+glfwCreateWindowSurface.
+
+
+## Caveats {#caveats}
+
+### Multiple sets of native access functions {#multiplatform_caveat}
+
+Because GLFW now supports runtime selection of platform (window system), a library binary
+may export native access functions for multiple platforms.  Starting with version 3.4 you
+must not assume that GLFW is running on a platform just because it exports native access
+functions for it.  After initialization, you can query the selected platform with @ref
+glfwGetPlatform.
+
+
+### Version string format has been changed {#version_string_caveat}
+
+Because GLFW now supports runtime selection of platform (window system), the version
+string returned by @ref glfwGetVersionString has been expanded.  It now contains the names
+of all APIs for all the platforms that the library binary supports.
+
+The version string is intended for bug reporting and should not be parsed.  See
+@ref glfwGetVersion and @ref glfwPlatformSupported instead.
+
+
+### Joystick support is initialized on demand {#joystick_init_caveat}
+
+The joystick part of GLFW is now initialized when first used, primarily to work
+around faulty Windows drivers that cause DirectInput to take up to several
+seconds to enumerate devices.
+
+This change is mostly not observable.  However, if your application waits for
+events without having first called any joystick function or created any visible
+windows, the wait may never unblock as GLFW may not yet have subscribed to
+joystick related OS events.
+
+To work around this, call any joystick function before waiting for events, for
+example by setting a [joystick callback](@ref joystick_event).
+
+
+### Tests and examples are disabled when built as a subproject {#standalone_caveat}
+
+GLFW now by default does not build the tests or examples when it is added as
+a subdirectory of another CMake project.  If you were setting @ref
+GLFW_BUILD_TESTS or @ref GLFW_BUILD_EXAMPLES to false in your CMake files, you
+can now remove this.
+
+If you do want these to be built, set @ref GLFW_BUILD_TESTS and @ref
+GLFW_BUILD_EXAMPLES in your CMake files before adding the GLFW subdirectory.
+
+```cmake
+set(GLFW_BUILD_EXAMPLES ON CACHE BOOL "" FORCE)
+set(GLFW_BUILD_TESTS ON CACHE BOOL "" FORCE)
+add_subdirectory(path/to/glfw)
+```
+
+
+### Configuration header is no longer generated {#config_header_caveat}
+
+The `glfw_config.h` configuration header is no longer generated by CMake and the
+platform selection macros are now part of the GLFW CMake target.  The
+`_GLFW_USE_CONFIG_H` macro is still supported in case you are generating
+a configuration header in a custom build setup.
+
+
+### Documentation generation requires Doxygen 1.9.8 or later {#docs_target_caveat}
+
+Doxygen 1.9.8 or later is now required for the `docs` CMake target to be
+generated.  This is because the documentation now uses more of the Markdown
+support in Doxygen and this support has until recently been relatively unstable.
+
+
+### Windows 7 framebuffer transparency requires DWM transparency {#win7_framebuffer_caveat}
+
+GLFW no longer supports per-pixel framebuffer transparency via @ref
+GLFW_TRANSPARENT_FRAMEBUFFER on Windows 7 if DWM transparency is off
+(the Transparency setting under Personalization > Window Color).
+
+
+### macOS main menu now created at initialization {#macos_menu_caveat}
+
+GLFW now creates the main menu and completes the initialization of NSApplication
+during initialization.  Programs that do not want a main menu can disable it
+with the [GLFW_COCOA_MENUBAR](@ref GLFW_COCOA_MENUBAR_hint) init hint.
+
+
+### macOS CoreVideo dependency has been removed {#corevideo_caveat}
+
+GLFW no longer depends on the CoreVideo framework on macOS and it no longer
+needs to be specified during compilation or linking.
+
+
+### Wayland framebuffer may lack alpha channel on older systems {#wayland_alpha_caveat}
+
+On Wayland, when creating an EGL context on a machine lacking the new
+`EGL_EXT_present_opaque` extension, the @ref GLFW_ALPHA_BITS window hint will be
+ignored and the framebuffer will not have an alpha channel.  This is because
+some Wayland compositors treat any buffer with an alpha channel as per-pixel
+transparent.
+
+If you want a per-pixel transparent window, see the
+[GLFW_TRANSPARENT_FRAMEBUFFER](@ref GLFW_TRANSPARENT_FRAMEBUFFER_hint) window
+hint.
+
+
+### X11 empty events no longer round-trip to server {#x11_emptyevent_caveat}
+
+Events posted with @ref glfwPostEmptyEvent now use a separate unnamed pipe
+instead of sending an X11 client event to the helper window.
+
+
+## Deprecations {#deprecations}
+
+### Windows XP and Vista support is deprecated {#winxp_deprecated}
+
+Support for Windows XP and Vista has been deprecated and will be removed in
+a future release.  Windows XP has been out of extended support since 2014.
+
+
+### Original MinGW support is deprecated {#mingw_deprecated}
+
+Support for the now unmaintained original MinGW distribution has been deprecated
+and will be removed in a future release.
+
+This does not apply to the much more capable MinGW-w64, which remains fully
+supported, actively maintained and available on many platforms.
+
+
+### OS X Yosemite support is deprecated {#yosemite_deprecated}
+
+Support for OS X 10.10 Yosemite and earlier has been deprecated and will be
+removed in a future release.  OS X 10.10 has been out of support since 2017.
+
+
+## Removals {#removals}
+
+### GLFW_VULKAN_STATIC CMake option has been removed {#vulkan_static_removed}
+
+This option was used to compile GLFW directly linked with the Vulkan loader, instead of
+using dynamic loading to get hold of `vkGetInstanceProcAddr` at initialization.  This is
+now done by calling the @ref glfwInitVulkanLoader function before initialization.
+
+If you need backward compatibility, this macro can still be defined for GLFW 3.4 and will
+have no effect.  The call to @ref glfwInitVulkanLoader can be conditionally enabled in
+your code by checking the @ref GLFW_VERSION_MAJOR and @ref GLFW_VERSION_MINOR macros.
+
+
+### GLFW_USE_WAYLAND CMake option has been removed {#use_wayland_removed}
+
+This option was used to compile GLFW for Wayland instead of X11.  GLFW now
+supports selecting the platform at run-time.  By default GLFW is compiled for
+both Wayland and X11 on Linux and other Unix-like systems.
+
+To disable Wayland or X11 or both, set the @ref GLFW_BUILD_WAYLAND and @ref
+GLFW_BUILD_X11 CMake options.
+
+The `GLFW_USE_WAYLAND` CMake variable must not be present in the CMake cache at
+all, or GLFW will fail to configure.  If you are getting this error, delete the
+CMake cache for GLFW and configure again.
+
+
+### GLFW_USE_OSMESA CMake option has been removed {#use_osmesa_removed}
+
+This option was used to compile GLFW for the Null platform.  The Null platform
+is now always available.  To produce a library binary that only supports this
+platform, the way this CMake option used to do, you will instead need to disable
+the default platforms for the target OS.  This means setting the @ref
+GLFW_BUILD_WIN32, @ref GLFW_BUILD_COCOA or @ref GLFW_BUILD_WAYLAND and @ref
+GLFW_BUILD_X11 CMake options to false.
+
+You can set all of them to false and the ones that don't apply for the target OS
+will be ignored.
+
+
+### wl_shell protocol support has been removed {#wl_shell_removed}
+
+Support for the deprecated wl_shell protocol has been removed and GLFW now only
+supports the XDG-Shell protocol.  If your Wayland compositor does not support
+XDG-Shell then GLFW will fail to initialize.
+

+# Getting started {#quick_guide}
+
+[TOC]
+
+This guide takes you through writing a small application using GLFW 3.  The
+application will create a window and OpenGL context, render a rotating triangle
+and exit when the user closes the window or presses _Escape_.  This guide will
+introduce a few of the most commonly used functions, but there are many more.
+
+This guide assumes no experience with earlier versions of GLFW.  If you
+have used GLFW 2 in the past, read @ref moving_guide, as some functions
+behave differently in GLFW 3.
+
+
+## Step by step {#quick_steps}
+
+### Including the GLFW header {#quick_include}
+
+In the source files of your application where you use GLFW, you need to include
+its header file.
+
+```c
+#include <GLFW/glfw3.h>
+```
+
+This header provides all the constants, types and function prototypes of the
+GLFW API.
+
+By default it also includes the OpenGL header from your development environment.
+On some platforms this header only supports older versions of OpenGL.  The most
+extreme case is Windows, where it typically only supports OpenGL 1.2.
+
+Most programs will instead use an
+[extension loader library](@ref context_glext_auto) and include its header.
+This example uses files generated by [glad](https://gen.glad.sh/).  The GLFW
+header can detect most such headers if they are included first and will then not
+include the one from your development environment.
+
+```c
+#include <glad/gl.h>
+#include <GLFW/glfw3.h>
+```
+
+To make sure there will be no header conflicts, you can define @ref
+GLFW_INCLUDE_NONE before the GLFW header to explicitly disable inclusion of the
+development environment header.  This also allows the two headers to be included
+in any order.
+
+```c
+#define GLFW_INCLUDE_NONE
+#include <GLFW/glfw3.h>
+#include <glad/gl.h>
+```
+
+
+### Initializing and terminating GLFW {#quick_init_term}
+
+Before you can use most GLFW functions, the library must be initialized.  On
+successful initialization, `GLFW_TRUE` is returned.  If an error occurred,
+`GLFW_FALSE` is returned.
+
+```c
+if (!glfwInit())
+{
+    // Initialization failed
+}
+```
+
+Note that `GLFW_TRUE` and `GLFW_FALSE` are and will always be one and zero.
+
+When you are done using GLFW, typically just before the application exits, you
+need to terminate GLFW.
+
+```c
+glfwTerminate();
+```
+
+This destroys any remaining windows and releases any other resources allocated by
+GLFW.  After this call, you must initialize GLFW again before using any GLFW
+functions that require it.
+
+
+### Setting an error callback {#quick_capture_error}
+
+Most events are reported through callbacks, whether it's a key being pressed,
+a GLFW window being moved, or an error occurring.  Callbacks are C functions (or
+C++ static methods) that are called by GLFW with arguments describing the event.
+
+In case a GLFW function fails, an error is reported to the GLFW error callback.
+You can receive these reports with an error callback.  This function must have
+the signature below but may do anything permitted in other callbacks.
+
+```c
+void error_callback(int error, const char* description)
+{
+    fprintf(stderr, "Error: %s\n", description);
+}
+```
+
+Callback functions must be set, so GLFW knows to call them.  The function to set
+the error callback is one of the few GLFW functions that may be called before
+initialization, which lets you be notified of errors both during and after
+initialization.
+
+```c
+glfwSetErrorCallback(error_callback);
+```
+
+
+### Creating a window and context {#quick_create_window}
+
+The window and its OpenGL context are created with a single call to @ref
+glfwCreateWindow, which returns a handle to the created combined window and
+context object
+
+```c
+GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", NULL, NULL);
+if (!window)
+{
+    // Window or OpenGL context creation failed
+}
+```
+
+This creates a 640 by 480 windowed mode window with an OpenGL context.  If
+window or OpenGL context creation fails, `NULL` will be returned.  You should
+always check the return value.  While window creation rarely fails, context
+creation depends on properly installed drivers and may fail even on machines
+with the necessary hardware.
+
+By default, the OpenGL context GLFW creates may have any version.  You can
+require a minimum OpenGL version by setting the `GLFW_CONTEXT_VERSION_MAJOR` and
+`GLFW_CONTEXT_VERSION_MINOR` hints _before_ creation.  If the required minimum
+version is not supported on the machine, context (and window) creation fails.
+
+You can select the OpenGL profile by setting the `GLFW_OPENGL_PROFILE` hint.
+This program uses the core profile as that is the only profile macOS supports
+for OpenGL 3.x and 4.x.
+
+```c
+glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
+glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
+glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
+GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", NULL, NULL);
+if (!window)
+{
+    // Window or context creation failed
+}
+```
+
+When a window and context is no longer needed, destroy it.
+
+```c
+glfwDestroyWindow(window);
+```
+
+Once this function is called, no more events will be delivered for that window
+and its handle becomes invalid.
+
+
+### Making the OpenGL context current {#quick_context_current}
+
+Before you can use the OpenGL API, you must have a current OpenGL context.
+
+```c
+glfwMakeContextCurrent(window);
+```
+
+The context will remain current until you make another context current or until
+the window owning the current context is destroyed.
+
+If you are using an [extension loader library](@ref context_glext_auto) to
+access modern OpenGL then this is when to initialize it, as the loader needs
+a current context to load from.  This example uses
+[glad](https://github.com/Dav1dde/glad), but the same rule applies to all such
+libraries.
+
+```c
+gladLoadGL(glfwGetProcAddress);
+```
+
+
+### Checking the window close flag {#quick_window_close}
+
+Each window has a flag indicating whether the window should be closed.
+
+When the user attempts to close the window, either by pressing the close widget
+in the title bar or using a key combination like Alt+F4, this flag is set to 1.
+Note that __the window isn't actually closed__, so you are expected to monitor
+this flag and either destroy the window or give some kind of feedback to the
+user.
+
+```c
+while (!glfwWindowShouldClose(window))
+{
+    // Keep running
+}
+```
+
+You can be notified when the user is attempting to close the window by setting
+a close callback with @ref glfwSetWindowCloseCallback.  The callback will be
+called immediately after the close flag has been set.
+
+You can also set it yourself with @ref glfwSetWindowShouldClose.  This can be
+useful if you want to interpret other kinds of input as closing the window, like
+for example pressing the _Escape_ key.
+
+
+### Receiving input events {#quick_key_input}
+
+Each window has a large number of callbacks that can be set to receive all the
+various kinds of events.  To receive key press and release events, create a key
+callback function.
+
+```c
+static void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods)
+{
+    if (key == GLFW_KEY_ESCAPE && action == GLFW_PRESS)
+        glfwSetWindowShouldClose(window, GLFW_TRUE);
+}
+```
+
+The key callback, like other window related callbacks, are set per-window.
+
+```c
+glfwSetKeyCallback(window, key_callback);
+```
+
+In order for event callbacks to be called when events occur, you need to process
+events as described below.
+
+
+### Rendering with OpenGL {#quick_render}
+
+Once you have a current OpenGL context, you can use OpenGL normally.  In this
+tutorial, a multicolored rotating triangle will be rendered.  The framebuffer
+size needs to be retrieved for `glViewport`.
+
+```c
+int width, height;
+glfwGetFramebufferSize(window, &width, &height);
+glViewport(0, 0, width, height);
+```
+
+You can also set a framebuffer size callback using @ref
+glfwSetFramebufferSizeCallback and be notified when the size changes.
+
+The details of how to render with OpenGL is outside the scope of this tutorial,
+but there are many excellent resources for learning modern OpenGL.  Here are
+a few of them:
+
+ - [Anton's OpenGL 4 Tutorials](https://antongerdelan.net/opengl/)
+ - [Learn OpenGL](https://learnopengl.com/)
+ - [Open.GL](https://open.gl/)
+
+These all happen to use GLFW, but OpenGL itself works the same whatever API you
+use to create the window and context.
+
+
+### Reading the timer {#quick_timer}
+
+To create smooth animation, a time source is needed.  GLFW provides a timer that
+returns the number of seconds since initialization.  The time source used is the
+most accurate on each platform and generally has micro- or nanosecond
+resolution.
+
+```c
+double time = glfwGetTime();
+```
+
+
+### Swapping buffers {#quick_swap_buffers}
+
+GLFW windows by default use double buffering.  That means that each window has
+two rendering buffers; a front buffer and a back buffer.  The front buffer is
+the one being displayed and the back buffer the one you render to.
+
+When the entire frame has been rendered, the buffers need to be swapped with one
+another, so the back buffer becomes the front buffer and vice versa.
+
+```c
+glfwSwapBuffers(window);
+```
+
+The swap interval indicates how many frames to wait until swapping the buffers,
+commonly known as _vsync_.  By default, the swap interval is zero, meaning
+buffer swapping will occur immediately.  On fast machines, many of those frames
+will never be seen, as the screen is still only updated typically 60-75 times
+per second, so this wastes a lot of CPU and GPU cycles.
+
+Also, because the buffers will be swapped in the middle the screen update,
+leading to [screen tearing](https://en.wikipedia.org/wiki/Screen_tearing).
+
+For these reasons, applications will typically want to set the swap interval to
+one.  It can be set to higher values, but this is usually not recommended,
+because of the input latency it leads to.
+
+```c
+glfwSwapInterval(1);
+```
+
+This function acts on the current context and will fail unless a context is
+current.
+
+
+### Processing events {#quick_process_events}
+
+GLFW needs to communicate regularly with the window system both in order to
+receive events and to show that the application hasn't locked up.  Event
+processing must be done regularly while you have visible windows and is normally
+done each frame after buffer swapping.
+
+There are two methods for processing pending events; polling and waiting.  This
+example will use event polling, which processes only those events that have
+already been received and then returns immediately.
+
+```c
+glfwPollEvents();
+```
+
+This is the best choice when rendering continually, like most games do.  If
+instead you only need to update your rendering once you have received new input,
+@ref glfwWaitEvents is a better choice.  It waits until at least one event has
+been received, putting the thread to sleep in the meantime, and then processes
+all received events.  This saves a great deal of CPU cycles and is useful for,
+for example, many kinds of editing tools.
+
+
+## Putting it together {#quick_example}
+
+Now that you know how to initialize GLFW, create a window and poll for
+keyboard input, it's possible to create a small program.
+
+This program creates a 640 by 480 windowed mode window and starts a loop that
+clears the screen, renders a triangle and processes events until the user either
+presses _Escape_ or closes the window.
+
+@snippet triangle-opengl.c code
+
+The program above can be found in the [source package][download] as
+`examples/triangle-opengl.c` and is compiled along with all other examples when
+you build GLFW.  If you built GLFW from the source package then you already have
+this as `triangle-opengl.exe` on Windows, `triangle-opengl` on Linux or
+`triangle-opengl.app` on macOS.
+
+[download]: https://www.glfw.org/download.html
+
+This tutorial used only a few of the many functions GLFW provides.  There are
+guides for each of the areas covered by GLFW.  Each guide will introduce all the
+functions for that category.
+
+ - @ref intro_guide
+ - @ref window_guide
+ - @ref context_guide
+ - @ref monitor_guide
+ - @ref input_guide
+
+You can access reference documentation for any GLFW function by clicking it and
+the reference for each function links to related functions and guide sections.
+
+The tutorial ends here.  Once you have written a program that uses GLFW, you
+will need to compile and link it.  How to do that depends on the development
+environment you are using and is best explained by the documentation for that
+environment.  To learn about the details that are specific to GLFW, see
+@ref build_guide.

+# Vulkan guide {#vulkan_guide}
+
+[TOC]
+
+This guide is intended to fill the gaps between the official [Vulkan
+resources](https://www.khronos.org/vulkan/) and the rest of the GLFW
+documentation and is not a replacement for either.  It assumes some familiarity
+with Vulkan concepts like loaders, devices, queues and surfaces and leaves it to
+the Vulkan documentation to explain the details of Vulkan functions.
+
+To develop for Vulkan you should download the [LunarG Vulkan
+SDK](https://vulkan.lunarg.com/) for your platform.  Apart from headers and link
+libraries, they also provide the validation layers necessary for development.
+
+The [Vulkan Tutorial](https://vulkan-tutorial.com/) has more information on how
+to use GLFW and Vulkan.  The [Khronos Vulkan
+Samples](https://github.com/KhronosGroup/Vulkan-Samples) also use GLFW, although
+with a small framework in between.
+
+For details on a specific Vulkan support function, see the @ref vulkan.  There
+are also guides for the other areas of the GLFW API.
+
+ - @ref intro_guide
+ - @ref window_guide
+ - @ref context_guide
+ - @ref monitor_guide
+ - @ref input_guide
+
+
+## Finding the Vulkan loader {#vulkan_loader}
+
+GLFW itself does not ever need to be linked against the Vulkan loader.
+
+By default, GLFW will load the Vulkan loader dynamically at runtime via its standard name:
+`vulkan-1.dll` on Windows, `libvulkan.so.1` on Linux and other Unix-like systems and
+`libvulkan.1.dylib` on macOS.
+
+@macos GLFW will also look up and search the `Frameworks` subdirectory of your
+application bundle.
+
+If your code is using a Vulkan loader with a different name or in a non-standard location
+you will need to direct GLFW to it.  Pass your version of `vkGetInstanceProcAddr` to @ref
+glfwInitVulkanLoader before initializing GLFW and it will use that function for all Vulkan
+entry point retrieval.  This prevents GLFW from dynamically loading the Vulkan loader.
+
+```c
+glfwInitVulkanLoader(vkGetInstanceProcAddr);
+```
+
+@macos To make your application be redistributable you will need to set up the application
+bundle according to the LunarG SDK documentation.  This is explained in more detail in the
+[SDK documentation for macOS](https://vulkan.lunarg.com/doc/sdk/latest/mac/getting_started.html).
+
+
+## Including the Vulkan header file {#vulkan_include}
+
+To have GLFW include the Vulkan header, define @ref GLFW_INCLUDE_VULKAN before including
+the GLFW header.
+
+```c
+#define GLFW_INCLUDE_VULKAN
+#include <GLFW/glfw3.h>
+```
+
+If you instead want to include the Vulkan header from a custom location or use
+your own custom Vulkan header then do this before the GLFW header.
+
+```c
+#include <path/to/vulkan.h>
+#include <GLFW/glfw3.h>
+```
+
+Unless a Vulkan header is included, either by the GLFW header or above it, the following
+GLFW functions will not be declared, as depend on Vulkan types.
+
+ - @ref glfwInitVulkanLoader
+ - @ref glfwGetInstanceProcAddress
+ - @ref glfwGetPhysicalDevicePresentationSupport
+ - @ref glfwCreateWindowSurface
+
+The `VK_USE_PLATFORM_*_KHR` macros do not need to be defined for the Vulkan part
+of GLFW to work.  Define them only if you are using these extensions directly.
+
+
+## Querying for Vulkan support {#vulkan_support}
+
+If you are linking directly against the Vulkan loader then you can skip this
+section.  The canonical desktop loader library exports all Vulkan core and
+Khronos extension functions, allowing them to be called directly.
+
+If you are loading the Vulkan loader dynamically instead of linking directly
+against it, you can check for the availability of a loader and ICD with @ref
+glfwVulkanSupported.
+
+```c
+if (glfwVulkanSupported())
+{
+    // Vulkan is available, at least for compute
+}
+```
+
+This function returns `GLFW_TRUE` if the Vulkan loader and any minimally
+functional ICD was found.
+
+If one or both were not found, calling any other Vulkan related GLFW function
+will generate a @ref GLFW_API_UNAVAILABLE error.
+
+
+### Querying Vulkan function pointers {#vulkan_proc}
+
+To load any Vulkan core or extension function from the found loader, call @ref
+glfwGetInstanceProcAddress.  To load functions needed for instance creation,
+pass `NULL` as the instance.
+
+```c
+PFN_vkCreateInstance pfnCreateInstance = (PFN_vkCreateInstance)
+    glfwGetInstanceProcAddress(NULL, "vkCreateInstance");
+```
+
+Once you have created an instance, you can load from it all other Vulkan core
+functions and functions from any instance extensions you enabled.
+
+```c
+PFN_vkCreateDevice pfnCreateDevice = (PFN_vkCreateDevice)
+    glfwGetInstanceProcAddress(instance, "vkCreateDevice");
+```
+
+This function in turn calls `vkGetInstanceProcAddr`.  If that fails, the
+function falls back to a platform-specific query of the Vulkan loader (i.e.
+`dlsym` or `GetProcAddress`).  If that also fails, the function returns `NULL`.
+For more information about `vkGetInstanceProcAddr`, see the Vulkan
+documentation.
+
+Vulkan also provides `vkGetDeviceProcAddr` for loading device-specific versions
+of Vulkan function.  This function can be retrieved from an instance with @ref
+glfwGetInstanceProcAddress.
+
+```c
+PFN_vkGetDeviceProcAddr pfnGetDeviceProcAddr = (PFN_vkGetDeviceProcAddr)
+    glfwGetInstanceProcAddress(instance, "vkGetDeviceProcAddr");
+```
+
+Device-specific functions may execute a little faster, due to not having to
+dispatch internally based on the device passed to them.  For more information
+about `vkGetDeviceProcAddr`, see the Vulkan documentation.
+
+
+## Querying required Vulkan extensions {#vulkan_ext}
+
+To do anything useful with Vulkan you need to create an instance.  If you want
+to use Vulkan to render to a window, you must enable the instance extensions
+GLFW requires to create Vulkan surfaces.
+
+To query the instance extensions required, call @ref
+glfwGetRequiredInstanceExtensions.
+
+```c
+uint32_t count;
+const char** extensions = glfwGetRequiredInstanceExtensions(&count);
+```
+
+These extensions must all be enabled when creating instances that are going to
+be passed to @ref glfwGetPhysicalDevicePresentationSupport and @ref
+glfwCreateWindowSurface.  The set of extensions will vary depending on platform
+and may also vary depending on graphics drivers and other factors.
+
+If it fails it will return `NULL` and GLFW will not be able to create Vulkan
+window surfaces.  You can still use Vulkan for off-screen rendering and compute
+work.
+
+If successful the returned array will always include `VK_KHR_surface`, so if
+you don't require any additional extensions you can pass this list directly to
+the `VkInstanceCreateInfo` struct.
+
+```c
+VkInstanceCreateInfo ici;
+
+memset(&ici, 0, sizeof(ici));
+ici.enabledExtensionCount = count;
+ici.ppEnabledExtensionNames = extensions;
+...
+```
+
+Additional extensions may be required by future versions of GLFW.  You should
+check whether any extensions you wish to enable are already in the returned
+array, as it is an error to specify an extension more than once in the
+`VkInstanceCreateInfo` struct.
+
+@macos MoltenVK is (as of July 2022) not yet a fully conformant implementation
+of Vulkan.  As of Vulkan SDK 1.3.216.0, this means you must also enable the
+`VK_KHR_portability_enumeration` instance extension and set the
+`VK_INSTANCE_CREATE_ENUMERATE_PORTABILITY_BIT_KHR` bit in the instance creation
+info flags for MoltenVK to show up in the list of physical devices.  For more
+information, see the Vulkan and MoltenVK documentation.
+
+
+## Querying for Vulkan presentation support {#vulkan_present}
+
+Not every queue family of every Vulkan device can present images to surfaces.
+To check whether a specific queue family of a physical device supports image
+presentation without first having to create a window and surface, call @ref
+glfwGetPhysicalDevicePresentationSupport.
+
+```c
+if (glfwGetPhysicalDevicePresentationSupport(instance, physical_device, queue_family_index))
+{
+    // Queue family supports image presentation
+}
+```
+
+The `VK_KHR_surface` extension additionally provides the
+`vkGetPhysicalDeviceSurfaceSupportKHR` function, which performs the same test on
+an existing Vulkan surface.
+
+
+## Creating the window {#vulkan_window}
+
+Unless you will be using OpenGL or OpenGL ES with the same window as Vulkan,
+there is no need to create a context.  You can disable context creation with the
+[GLFW_CLIENT_API](@ref GLFW_CLIENT_API_hint) hint.
+
+```c
+glfwWindowHint(GLFW_CLIENT_API, GLFW_NO_API);
+GLFWwindow* window = glfwCreateWindow(640, 480, "Window Title", NULL, NULL);
+```
+
+See @ref context_less for more information.
+
+
+## Creating a Vulkan window surface {#vulkan_surface}
+
+You can create a Vulkan surface (as defined by the `VK_KHR_surface` extension)
+for a GLFW window with @ref glfwCreateWindowSurface.
+
+```c
+VkSurfaceKHR surface;
+VkResult err = glfwCreateWindowSurface(instance, window, NULL, &surface);
+if (err)
+{
+    // Window surface creation failed
+}
+```
+
+If an OpenGL or OpenGL ES context was created on the window, the context has
+ownership of the presentation on the window and a Vulkan surface cannot be
+created.
+
+It is your responsibility to destroy the surface.  GLFW does not destroy it for
+you.  Call `vkDestroySurfaceKHR` function from the same extension to destroy it.
