C SPECIFICATION    [Toc]    [Back]

			     int *errorBase,
			     int *eventBase )

PARAMETERS    [Toc]    [Back]

     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    [Toc]    [Back]

     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.
