C SPECIFICATION

10       GLboolean gluCheckExtension( const GLubyte *extName,
11                                    const GLubyte *extString )

PARAMETERS

15       extName    Specifies an extension name.

18                  ported.

DESCRIPTION

21       gluCheckExtension returns GL_TRUE if  extName  is  supported  otherwise
22       GL_FALSE is returned.
23
24       This is used to check for the presence for OpenGL, GLU or GLX extension
25       names  by  passing  the  extension  strings  returned  by  glGetString,
26       gluGetString,  glXGetClientString,  glXQueryExtensionsString,  or  glX‐
27       QueryServerString, respectively, as extString.
28

NOTES

30       Cases where one extension name is a substring of another are  correctly
31       handled.
32
33       There may or may not be leading or trailing blanks in extString.
34
35       Extension names should not contain embedded spaces.
36
37       All strings are null-terminated.
