The <code class="methodname">DB_ENV-&gt;mutex_stat_print()</code> method displays the mutex subsystem
statistical information, as described for the <code class="methodname">DB_ENV-&gt;mutex_stat()</code>

the <a class="xref" href="envset_msgfile.html" title="DB_ENV-&gt;set_msgfile()">DB_ENV-&gt;set_msgfile()</a>
method for more information), or passed to an application callback
function (see the <a class="xref" href="envset_msgcall.html" title="DB_ENV-&gt;set_msgcall()">DB_ENV-&gt;set_msgcall()</a>
method for more information).
