NAME
       waffle_get_proc_address - Query address of OpenGL functions


SYNOPSIS
       #include <waffle.h>

       void* waffle_get_proc_address(const char *name);


DESCRIPTION
       waffle_get_proc_address()
           On GLX, this redirects to glXGetProcAddress(3). On EGL, this redirects to eglGetProcAddress(3). On
           CGL, this function returns NULL because there exists no CGLGetProcAdress(). On WGL, this redirects to
           wglGetProcAddress(3).

           Some aspects of this function's behavior are platform-specific and non-intuitive. For example,

           •   If the queried function is not available, waffle_get_proc_address() may return a non-null
               pointer.

           •   If the queried function is statically exposed by the OpenGL library of a given API, then
               waffle_get_proc_address() may return a NULL.

           •   Under Windows (WGL) a current context must be available before executing the function. Otherwise
               waffle_get_proc_address() may return a NULL.

           For details on this function's behavior, see the specification for the relevant platform: the GLX 1.4
           Specification[1] the EGL 1.4 Specification[2] or the MSDN article[3].
