Overview
Windows users new to OpenGL should note that, for historical reasons, GL functions added after OpenGL version 1.1 are not available by default. Those functions must be loaded at run-time, either with an OpenGL extension-handling library or with
SDL_GL_GetProcAddress () and its related functions.
SDL_GLContext
is opaque to the application.
Function parameters
- window
-
the window to associate with the context.
Return value
( SDL_GLContext ) Returns the OpenGL context associated with window or NULL on failure; call SDL_GetError () for more information.
Thread safety
This function should only be called on the main thread.
