glXWaitX(3G)

NAME
     glXWaitX - complete X execution prior to subsequent OpenGL calls


C SPECIFICATION
     void glXWaitX( void )



DESCRIPTION
     X rendering calls made prior to glXWaitX are guaranteed to be executed
     before OpenGL rendering calls made after glXWaitX.  Although this 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 OpenGL 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     current context of the calling thread is a window, and that window is no
     longer valid.
