glXWaitGL(3G)

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     current context of the calling thread is a window, and that window is no
     longer valid.
