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.
