        <para>
            X rendering calls made prior to <function>glXWaitX</function> are guaranteed to be
            executed before GL rendering calls made after <function>glXWaitX</function>.
            Although the same result can be achieved using <function>XSync</function>,
            <function>glXWaitX</function> 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.
        </para>
        <para>
            <function>glXWaitX</function> is ignored if there is no current GLX context.

            <function>glXWaitX</function> may or may not flush the GL stream.

            <constant>GLXBadCurrentWindow</constant> is generated if the drawable associated
