* **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.**
|
||||
*
|

* 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
|
