<p class="Body"><a name="80688" class="autotag"> </a>This command displays statistics about system-wide usage of STREAMS message blocks.  It displays the size of the message block (under the column head <b>Size</b>), the number of message blocks available for this size (<b>Avail</b>), the number of message blocks of this size in use (<b>InUse</b>), the total number of message blocks allocated for this size (<b>Total</b>), the total memory usage by message blocks of this size (<b>Total mem</b>), the number of allocation requests that have failed for this message block size (<b>FailCnt</b>), the number of calls to <b class="routine"><i class="routine">bufcall</i></b><b>(&nbsp;)</b> pending due to <b class="routine"><i class="routine">allocb</i></b><b>(&nbsp;)</b> failure for message blocks of this size (<b>Bufcalls</b>). </p>
