MirBSD manpage: glXWaitGL(3)

GLXWAITGL()         UNIX Programmer's Manual          GLXWAITGL()

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     and that window is no longer valid.

SEE ALSO

     glFinish, glFlush, glXWaitX, XSync
