glFinish — block until all GL execution is complete
void glFinish( | void); |
glFinish does not return until the effects of all previously called GL commands are complete. Such effects include all changes to GL state, all changes to connection state, and all changes to the frame buffer contents.
glFinish requires a round trip to the server.
