 *
 * This file should be included as
 *        #include <KHR/khrplatform.h>
 * by Khronos client API header files that use its types and defines.
 *
 * The types in khrplatform.h should only be used to define API-specific types.
 *
 * Types defined in khrplatform.h:
 *    khronos_int8_t              signed   8  bit
 *    khronos_uint8_t             unsigned 8  bit
 *    khronos_int16_t             signed   16 bit
 *    khronos_uint16_t            unsigned 16 bit
 *    khronos_int32_t             signed   32 bit
 *    khronos_uint32_t            unsigned 32 bit
 *    khronos_int64_t             signed   64 bit
 *    khronos_uint64_t            unsigned 64 bit
 *    khronos_intptr_t            signed   same number of bits as a pointer
 *    khronos_uintptr_t           unsigned same number of bits as a pointer
 *    khronos_ssize_t             signed   size
 *    khronos_usize_t             unsigned size
 *    khronos_float_t             signed   32 bit floating point
 *    khronos_time_ns_t           unsigned 64 bit time in nanoseconds
 *    khronos_utime_nanoseconds_t unsigned time interval or absolute time in
 *                                         nanoseconds
 *    khronos_stime_nanoseconds_t signed time interval in nanoseconds
 *    khronos_boolean_enum_t      enumerated boolean type. This should
 *      only be used as a base type when a client API's boolean type is
 *      an enum. Client APIs which use an integer or other type for
 *      booleans cannot use this as the base type for their boolean.
 *
 * Tokens defined in khrplatform.h:
 *
 *    KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
 *
 *    KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
 *    KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
 *
 * Calling convention macros defined in this file:
 *    KHRONOS_APICALL
 *    KHRONOS_APIENTRY
 *    KHRONOS_APIATTRIBUTES
 *
 * These may be used in function prototypes as:
 *

@section compile_mingw_cross Cross-compilation with CMake and MinGW
 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.
@code{.sh}
 cmake -S path/to/glfw -B path/to/build -D CMAKE_TOOLCHAIN_FILE=path/to/file
@endcode
 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:
@code{.sh}
 cmake -S path/to/glfw -B path/to/build -D CMAKE_TOOLCHAIN_FILE=CMake/x86_64-w64-mingw32.cmake
@endcode
 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](https://cmake.org/cmake/help/latest/manual/cmake-toolchains.7.html).

 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 linking the Vulkan loader directly with your application then you
 must also define @b _GLFW_VULKAN_STATIC.  Otherwise, GLFW will attempt to use the
 external version.
 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.
 For the EGL context creation API, the following options are available:
 - @b _GLFW_USE_EGLPLATFORM_H to use an existing `EGL/eglplatform.h` header file
   for native handle types (fallback)
@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.

@subsection platform Runtime platform selection
 GLFW can be compiled for more than one platform (window system) at once.  This lets
 a single library binary support both X11 and Wayland 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.
@code
 glfwInitHint(GLFW_PLATFORM, GLFW_PLATFORM_X11);
@endcode
 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.
@code
 glfwInitHint(GLFW_PLATFORM, GLFW_PLATFORM_NULL);
@endcode
 You can test whether a library binary was compiled with support for a specific platform
 with @ref glfwPlatformSupported.
@code
 if (glfwPlatformSupported(GLFW_PLATFORM_WAYLAND))
    glfwInitHint(GLFW_PLATFORM, GLFW_PLATFORM_WAYLAND);
@endcode
 Once GLFW has been initialized, you can query which platform was selected with @ref
 glfwGetPlatform.
@code
 int platform = glfwGetPlatform();
@endcode
 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.
@subsection init_allocator Custom heap memory allocator
 The heap memory allocator can be customized before initialization with @ref
 glfwInitAllocator.
@code
 GLFWallocator allocator;
 allocator.allocate = my_malloc;
 allocator.reallocate = my_realloc;
 allocator.deallocate = my_free;
 allocator.user = NULL;
 glfwInitAllocator(&allocator);
@endcode
 The allocator will be picked up at the beginning of initialization and will be
 used until GLFW 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.
@code

  header and it will detect this
 On some platforms supported by GLFW the OpenGL header and link library only
 expose older versions of OpenGL.  The most extreme case is Windows, which only
 exposes OpenGL 1.2.  The easiest way to work around this is to use an
 [extension loader library](@ref context_glext_auto).
 If you are using such a library then you should include its header _before_ the
 GLFW header.  This lets it replace the OpenGL header included by GLFW without
 conflicts.  This example uses
 [glad2](https://github.com/Dav1dde/glad), but the same rule applies to all such
 libraries.
@code
 #include <glad/gl.h>
 #include <GLFW/glfw3.h>
@endcode
 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.

 #define GLFW_INCLUDE_NONE
