NAME
     glXQueryExtension - indicate whether the GLX extension is supported


C SPECIFICATION
     Bool glXQueryExtension( Display *dpy,
                             int *errorBase,
                             int *eventBase )

DESCRIPTION
     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.

     errorBase and eventBase do not return values if they are specified as
     NULL.


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