glutExtensionSupported man page

glutExtensionSupported — Determine if an OpenGL extension is available.

Library

OpenGLUT - opengl

Synopsis

#include <openglut.h>

int
glutExtensionSupported(const char *extension);

Parameters


extension


A string-name of an extension.

Description

Returns 0 if OpenGLUT cannot determine that the requested extension is definitely present. Only checks extensions from glGetString().

Todo

Wouldn't this be simpler and clearer if we used strtok()?

Consider an ogWarning() if there is no current rendering context.

This is an ugly bit of code with 3 return statements, one of which is never reached.
