However, since XSync() requires a two way communication with the other X server, eliminating unnecessary XSync() calls is a key performance optimization. Support for this optimization is provided in #dmxsync.c. This file provides routines that evaluate this optimization by counting the number of XSync() calls and monitoring their latency. This functionality can be turned on using the -stat command-line parameter.<hr><h2>Typedef Documentation</h2> +<a class="anchor" name="a0" doxytag="dmxstat.c::DMXStatAvg" ></a><p> +<table class="mdTable" width="100%" cellpadding="2" cellspacing="0"> + <tr> + <td class="mdRow"> + <table cellpadding="0" cellspacing="0" border="0"> + <tr> + <td class="md" nowrap valign="top"> typedef struct <a class="el" href="struct__DMXStatAvg.html">_DMXStatAvg</a> <a class="el" href="struct__DMXStatAvg.html">DMXStatAvg</a> + </table> + </td> + </tr> +</table> +<table cellspacing=5 cellpadding=0 border=0> + <tr> + <td> + + </td> + <td> + +<p> +Used to compute a running average of value. </td> + </tr> +</table> +<hr><h2>Function Documentation</h2> +<a class="anchor" name="a6" doxytag="dmxstat.c::dmxStatActivate" ></a><p> +<table class="mdTable" width="100%" cellpadding="2" cellspacing="0"> + <tr> + <td class="mdRow"> + <table cellpadding="0" cellspacing="0" border="0"> + <tr> + <td class="md" nowrap valign="top"> void dmxStatActivate </td> + <td class="md" valign="top">( </td> + <td class="md" nowrap valign="top">const char * </td> + <td class="mdname" nowrap> <em>interval</em>, </td> + </tr> + <tr> + <td></td> + <td></td> + <td class="md" nowrap>const char * </td> + <td class="mdname" nowrap> <em>displays</em></td> + </tr> + <tr> + <td></td> + <td class="md">) </td> + <td class="md" colspan="2"></td> + </tr> + + </table> + </td> + </tr> +</table> +<table cellspacing=5 cellpadding=0 border=0> + <tr> + <td> + + </td> + <td> + +<p> +Turn on XSync statistic gathering and printing.
