The <code class="methodname">DbEnv::memp_stat_print()</code> method displays cache
subsystem statistical information, as described for the
<a class="xref" href="mempstat.html" title="DbEnv::memp_stat()">
<span>DbEnv::memp_stat()</span>
</a> method. The information is printed to
a specified output channel (see the
<a class="xref" href="envset_msgfile.html" title="DbEnv::set_msgfile()">
<span>DbEnv::set_msgfile()</span>
</a> method for more
information), or passed to an application callback function (see the
<a class="xref" href="envset_msgcall.html" title="DbEnv::set_msgcall()">
<span>DbEnv::set_msgcall()</span>
</a> method for more
information).

called.

<p>
The <code class="methodname">DbEnv::memp_stat_print()</code> <span>

exception that encapsulates a non-zero error value on
failure, and returns 0 on success.
