<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#a7">dmxSyncActivate()</a> before <a class="el" href="dmxsync_8c.html#a8">dmxSyncInit()</a> was called, then no XSync() batching is performed and this function always calles XSync() immediately.<p>
(Note that this function uses TimerSet but works correctly in the face of a server generation. See the source for details.)<p>
If <em>dmxScreen</em> is <em>NULL</em>, then all pending syncs will be flushed immediately.     </td>

<p>
Request the XSync() batching optimization with the specified <em>interval</em> (in mS). If the <em>interval</em> is 0, 100mS is used. If the <em>interval</em> is less than 0, then the XSync() batching optimization is not requested (e.g., so the -syncbatch -1 command line option can turn off the default 100mS XSync() batching).<p>
Note that the parameter to this routine is a string, since it will usually be called from <a class="el" href="dmxinit_8c.html#a40">ddxProcessArgument</a> in #dmxinit.c     </td>
