glXWaitX  -  complete  X  execution prior to subsequent GL
       calls



C SPECIFICATION

       void glXWaitX( void )



DESCRIPTION

       X rendering calls made prior to glXWaitX are guaranteed to
       be executed before GL rendering calls made after glXWaitX.
       Although the same result  can  be  achieved  using  XSync,
       glXWaitX  does not require a round trip to the server, and
       it is therefore more efficient in cases where  client  and
       server are on separate machines.

       glXWaitX is ignored if there is no current GLX context.


NOTES

       glXWaitX may or may not flush the GL stream.


ERRORS

       GLXBadCurrentWindow  is  generated if the drawable associ-
       ated with the current context of the calling thread  is  a
       window, and that window is no longer valid.
