glXWaitGL  -  complete  GL execution prior to subsequent X
       calls



C SPECIFICATION

       void glXWaitGL( void )



DESCRIPTION

       GL rendering calls made prior to glXWaitGL are  guaranteed
       to  be  executed  before  X  rendering  calls  made  after
       glXWaitGL.  Although this  same  result  can  be  achieved
       using glFinish, glXWaitGL 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.

       glXWaitGL is ignored if there is no current GLX context.


NOTES

       glXWaitGL may or may not flush the X 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       window, and that window is no longer valid.
