+/*! @file glfw3native.h
+ *  @brief The header of the native access functions.
+ *
+ *  This is the header file of the native access functions.  See @ref native for
+ *  more information.
+ */
+/*! @defgroup native Native access
+ *  @brief Functions related to accessing native handles.
+ *
+ *  **By using the native access functions you assert that you know what you're
+ *  doing and how to fix problems caused by using them.  If you don't, you
+ *  shouldn't be using them.**
+ *
+ *  Before the inclusion of @ref glfw3native.h, you may define zero or more
+ *  window system API macro and zero or more context creation API macros.
+ *
+ *  The chosen backends must match those the library was compiled for.  Failure
+ *  to do this will cause a link-time error.
+ *
+ *  The available window API macros are:
+ *  * `GLFW_EXPOSE_NATIVE_WIN32`
+ *  * `GLFW_EXPOSE_NATIVE_COCOA`
+ *  * `GLFW_EXPOSE_NATIVE_X11`
+ *  * `GLFW_EXPOSE_NATIVE_WAYLAND`
+ *
+ *  The available context API macros are:
+ *  * `GLFW_EXPOSE_NATIVE_WGL`
+ *  * `GLFW_EXPOSE_NATIVE_NSGL`
+ *  * `GLFW_EXPOSE_NATIVE_GLX`
+ *  * `GLFW_EXPOSE_NATIVE_EGL`
+ *  * `GLFW_EXPOSE_NATIVE_OSMESA`
+ *
+ *  These macros select which of the native access functions that are declared
+ *  and which platform-specific headers to include.  It is then up your (by
+ *  definition platform-specific) code to handle which of these should be
+ *  defined.
+ *
+ *  If you do not want the platform-specific headers to be included, define
+ *  `GLFW_NATIVE_INCLUDE_NONE` before including the @ref glfw3native.h header.
+ *
+ *  @code
