NAMEglutGetProcAddress — Determine if an OpenGLUT feature or extension is
available.
LIBRARY
OpenGLUT - openglut
SYNOPSIS
#include <openglut.h>
void
glutGetProcAddress(const char *procName);
PARAMETERS
procName Procedure name.
DESCRIPTION
Given a function name, searches for the function (or "procedure", hence
"Proc") in internal tables. If the function is found, a pointer to the
function is returned. If the function is not found, NULL is returned.
In addition to an internal OpenGLUT table, this function will also con‐
sult glX (on X systems) or wgl (on WIN32 and WINCE), if the OpenGLUT
tables do not have the requested function. It should return any OpenGL,
glX, or wgl function if those functions are available.
CAVEATS
The code makes no effort towards efficiency. It is advised that you cache
the pointer retrieved from this function if you need a certain function
repeatedly.
