/*! @defgroup native Native access
|
|
*
|
|
* **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 must define exactly one
|
|
* window system API macro and exactly one context creation API macro. Failure
|
|
* to do this will cause a compile-time error.
|
|
*
|
|
* The available window API macros are:
|
|
* * `GLFW_EXPOSE_NATIVE_WIN32`
|
|
* * `GLFW_EXPOSE_NATIVE_COCOA`
|
|
* * `GLFW_EXPOSE_NATIVE_X11`
|
|
*
|
|
* The available context API macros are:
|
|
* * `GLFW_EXPOSE_NATIVE_WGL`
|
|
* * `GLFW_EXPOSE_NATIVE_NSGL`
|
|
* * `GLFW_EXPOSE_NATIVE_GLX`
|
|
* * `GLFW_EXPOSE_NATIVE_EGL`
|
|
*
|
|
* 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.
