complete X execution prior to subsequent GL calls
void glXWaitX( | void) ; |
X rendering calls made prior to glXWaitX
are guaranteed to be
executed before GL rendering calls made after glXWaitX
.
Although the 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.
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window is no longer valid.
