glXWaitGL(3G) OpenGL Reference - GLX glXWaitGL(3G)
NAME
glXWaitGL - complete GL execution prior to subsequent X calls
C SPECIFICATION
void glXWaitGL( void )
DESCRIPTION
OpenGL 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current context of the calling thread is a window, and that window is no
longer valid.
SEE ALSO
glFinish, glFlush, glXWaitX, XSync
