*
* 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.
