For each group displayed on thenode, this routine lists only members added (using <b><a href="./msgQDistGrpLib.html#msgQDistGrpAdd">msgQDistGrpAdd</a>( )</b>) from thenode executing the <b><a href="./msgQDistGrpShow.html#msgQDistGrpShow">msgQDistGrpShow</a>( )</b> call. <p>If <i>distGrpName</i> is NULL, all groups and their locally addedmembers are displayed. Otherwise, only the group specified by <i>distGrpName</i> and its locally added members are displayed.<p></blockquote><h4>NOTE</h4><blockquote><p>The concept of "locally added" is an important one. All nodes in the system can add groups to a message queue group. However, only those messagequeues (including remote distributed message queues) that were added to the group from the local node are displayed by this routine.<p></blockquote><h4>EXAMPLE</h4><blockquote><p><p><pre>-> msgQDistGrpShow(0)NAME OF GROUP GROUP ID STATE MEMBER ID TYPE OF MEMBER------------------- ---------- ------- ---------- ---------------------------grp1 0x3ff9e3 global 0x3ff98b distributed msg queue 0x3ff9fb distributed msg queuegrp2 0x3ff933 global 0x3ff89b distributed msg queue 0x3ff8db distributed msg queue 0x3ff94b distributed msg queuevalue = 0 = 0x0</pre></blockquote><h4>AVAILABILITY</h4><blockquote><p>This routine is distributed as a component of the unbundled distributedmessage queues option, VxFusion.<p></blockquote><h4>RETURNS</h4><blockquote><p>OK, unless name not found.<p></blockquote><h4>ERRNO</h4><blockquote><p><p><dl><dt><b>S_msgQDistGrpLib_NO_MATCH</b><dd>The group name was not found in the database.</dl></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./msgQDistGrpShow.html#top">msgQDistGrpShow</a></b></body></html>⌨️ 快捷键说明
