/*! @defgroup native Native access
|
|
*
|
|
* **By using the native API, you assert that you know what you're doing and
|
|
* how to fix problems caused by using it. If you don't, you shouldn't be
|
|
* using it.**
|
|
*
|
|
* Before the inclusion of @ref glfw3native.h, you must define exactly one
|
|
* window API macro and exactly one context 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.
