GLXWAITX(3)GLXWAITX(3)NAMEglXWaitX - complete X execution prior to subsequent GL calls
C SPECIFICATION
void glXWaitX( void )
delim $$
DESCRIPTION
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.
NOTESglXWaitX may or may not flush the GL 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no longer valid.
