15 extName Specifies an extension name.
16
17 extString Specifies a space-separated list of extension names sup‐
18 ported.

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
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.
