NAME
       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.
