NAME
       glXQueryExtension - indicate whether the GLX extension is supported

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

PARAMETERS
       dpy
	   Specifies the connection to the X server.

       errorBase
	   Returns the base error code of the GLX server extension.

       eventBase
	   Returns the base event code of the GLX server extension.

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. These values should be added to the constant error and
       event values to determine the actual event or error values. Otherwise, errorBase and eventBase are unchanged.

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