NAME

6       gluCheckExtension - determines if an extension name is supported
7

C SPECIFICATION

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

PARAMETERS

13       extName
14           Specifies an extension name.
15
16       extString
17           Specifies a space-separated list of extension names supported.
18

DESCRIPTION

20       gluCheckExtension returns GLU_TRUE if extName is supported otherwise
21       GLU_FALSE is returned.
22
23       This is used to check for the presence for OpenGL, GLU, or GLX
24       extension names by passing the extension strings returned by
25       glGetString(), gluGetString(), glXGetClientString(),
26       glXQueryExtensionsString(), or glXQueryServerString(), respectively, as
27       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.
