glXWaitGL -- complete GL execution prior to subsequent X calls
void glXWaitGL(void void)
OpenGL 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.
glXWaitGL may or may not flush the X stream.
GLX_BAD_CURRENT_WINDOW is generated if the drawable associated with the
current context of the calling thread is a window, and that window is no
