DESCRIPTION

24       glXQueryExtension  returns  True if the X server of connection dpy sup‐
25       ports the GLX extension, False otherwise.  If True  is  returned,  then
26       errorBase and eventBase return the error base and event base of the GLX
27       extension.  Otherwise, errorBase and eventBase are unchanged.
28

30       NULL.

NOTES

33       eventBase  is  included  for future extensions.  GLX does not currently
34       define any events.
