<p>Request an XSync() to the display used by <em>dmxScreen</em>. If <em>now</em> is TRUE, call XSync() immediately instead of waiting for the next XSync() batching point. Note that if XSync() batching was deselected with <a class="el" href="dmxsync_8c.html#ae0a769161d6f8d88067a9cac16f9cf6f">dmxSyncActivate()</a> before <a class="el" href="dmxsync_8c.html#a0b349896e58d4291d712e31121fdc0ac">dmxSyncInit()</a> was called, then no XSync() batching is performed and this function always calles XSync() immediately.</p>
<p>(Note that this function uses TimerSet but works correctly in the face of a server generation. See the source for details.)</p>
<p>If <em>dmxScreen</em> is <em>NULL</em>, then all pending syncs will be flushed immediately. </p>
