Although this same result can be achieved using \f3glFinish\fP, \f3glXWaitGL\fP 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. .P \f3glXWaitGL\fP is ignored if there is no current GLX context. .SH NOTES \f3glXWaitGL\fP may or may not flush the X stream. .SH ERRORS \f3GLXBadCurrentWindow\fP is generated if the drawable associated with the current context of the calling thread is a window, and that window is no longer valid. .SH SEE ALSO \f3glFinish\fP, \f3glFlush\fP, \f3glXWaitX\fP, \f3XSync\fP
