gluCheckExtension
determines if an extension name is supported
C Specification
GLboolean gluCheckExtension
const GLubyte * extName
const GLubyte * extString
Parameters
extName
Specifies an extension name.
extString
Specifies a space-separated list of extension names supported.
Description
gluCheckExtension returns GLU_TRUE if extName is supported otherwise
GLU_FALSE is returned.
This is used to check for the presence for OpenGL, GLU, or GLX extension names
by passing the extension strings returned by glGetString,
gluGetString, glXGetClientString,
glXQueryExtensionsString, or glXQueryServerString,
respectively, as extString.
Notes
Cases where one extension name is a substring of another are
correctly handled.
There may or may not be leading or trailing blanks in extString.
Extension names should not contain embedded spaces.
All strings are null-terminated.
