GLXWAITGL(3G)							   OpenGL Manual						     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       no longer valid.
