GLXWAITX()																GLXWAITX()

NAME
       glXWaitX - complete X execution prior to subsequent GL calls

C SPECIFICATION
       void glXWaitX( void )

       delim $$

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 associated with the current context of the calling thread is a window, and that window is
       no longer valid.
