NAME

6       waffle_get_proc_address - Query address of OpenGL functions
7

SYNOPSIS

9       #include <waffle.h>
10
11
12       void* waffle_get_proc_address(const char *name);
13

DESCRIPTION

15       waffle_get_proc_address()
16           On GLX, this redirects to glXGetProcAddress(3). On EGL, this
17           redirects to eglGetProcAddress(3). On CGL, this function returns
18           NULL because there exists no CGLGetProcAdress(). On WGL, this
19           redirects to wglGetProcAddress(3).
20
21           Some aspects of this function's behavior are platform-specific and
22           non-intuitive. For example,
23
24           ·   If the queried function is not available,
25               waffle_get_proc_address() may return a non-null pointer.
26
27           ·   If the queried function is statically exposed by the OpenGL
28               library of a given API, then waffle_get_proc_address() may
29               return a NULL.
30
31           ·   Under Windows (WGL) a current context must be available before
32               executing the function. Otherwise waffle_get_proc_address() may
33               return a NULL.
34
35           For details on this function's behavior, see the specification for
36           the relevant platform: the GLX 1.4 Specification[1] the EGL 1.4
37           Specification[2] or the MSDN article[3].
