It also shows the number of blocks currentlyallocated, and the average allocated block size.<p>If <i>type</i> is 1, it displays a list of all the blocks in the free list ofthe shared memory system partition.<p></blockquote><h4>WARNING</h4><blockquote><p>This routine locks access to the shared memory system partition whiledisplaying the information. This can compromise the access time tothe partition from other CPUs in the system. Generally, this routine isused for debugging purposes only.<p></blockquote><h4>EXAMPLE</h4><blockquote><p><pre> -> smMemShow 1 FREE LIST: num addr size --- ---------- ---------- 1 0x4ffef0 264 2 0x4fef18 1700 SUMMARY: status bytes blocks ave block max block --------------- --------- -------- ---------- ---------- current free 1964 2 982 1700 alloc 2356 1 2356 - cumulative alloc 2620 2 1310 - value = 0 = 0x0</pre></blockquote><h4>AVAILABILITY</h4><blockquote><p>This routine is distributed as a component of the unbundled shared memoryobjects support option, VxMP.<p></blockquote><h4>RETURNS</h4><blockquote><p>N/A<p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./smMemShow.html#top">smMemShow</a></b>, <b><a href="../../tornado/tools/windsh.html#top" >windsh</a></b>, chapter on target shell in<i>VxWorks Programmer's Guide, </i><i>Tornado User's Guide: Shell</i></body></html>⌨️ 快捷键说明
