20 Given a function name, searches for the function (or "procedure", hence
21 "Proc") in internal tables. If the function is found, a pointer to the
22 function is returned. If the function is not found, NULL is returned.
23
24 In addition to an internal OpenGLUT table, this function will also con‐
25 sult glX (on X systems) or wgl (on WIN32 and WINCE), if the OpenGLUT
26 tables do not have the requested function. It should return any OpenGL,
27 glX, or wgl function if those functions are available.
28
30 The code makes no effort towards efficiency. It is advised that you cache
31 the pointer retrieved from this function if you need a certain function
32 repeatedly.
