LIBRARY

OpenGLUT - openglut  

SYNOPSIS

In openglut.h Ft void Fn glutGetProcAddress const char *procName  

PARAMETERS

Bf Em
 procName Ef
    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, Bf Sy
 NULL Ef
 is returned.

In addition to an internal OpenGLUT table, this function will also consult 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.
