NAME
glXWaitX - complete X execution prior to subsequent OpenGL calls
C SPECIFICATION
void glXWaitX( void )
DESCRIPTION
X rendering calls made prior to glXWaitX are guaranteed to be executed before OpenGL rendering calls made after glXWaitX. Although this 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.
NOTES
glXWaitX may or may not flush the OpenGL stream.
ERRORS
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is generated if the drawable associated with the current context of the calling thread is a window, and that window is no longer valid.
