glXWaitGL()glXWaitGL()NAMEglXWaitGL - complete GL execution prior to subsequent X calls
SYNOPSIS
void glXWaitGL(
void );
DESCRIPTION
GL rendering calls made prior to glXWaitGL() are guaranteed to be exe‐
cuted 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.
NOTESglXWaitGL() 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no longer valid.
