int *eventBase )
- dpy
- Specifies the connection to the X server.

- Returns the base event code of the GLX server extension.
glXQueryExtension returns True if the X server of connection
dpy supports the GLX extension, False otherwise. If True
is returned, then errorBase and eventBase return the error base
and event base of the GLX extension. Otherwise, errorBase and
eventBase are unchanged.

are specified as NULL.
eventBase is included for future extensions. GLX does not currently
define any events.
