glXWaitGL 3G
glXWaitGL complete GL execution prior to subsequent X calls

## C Specification

void `glXWaitGL` void

## Description

GL 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.

## Notes

`glXWaitGL` may or may not flush the X 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is generated if the drawable associated with the current context of the calling thread is a window, and that window is no longer valid.
