The <code class="methodname">DB_ENV->lock_stat_print()</code> method displays the locking subsystem
statistical information, as described for the <code class="methodname">DB_ENV->lock_stat()</code>
method. The information is printed to a specified output channel (see
the <a class="xref" href="envset_msgfile.html" title="DB_ENV->set_msgfile()">DB_ENV->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->set_msgcall()">DB_ENV->set_msgcall()</a>
method for more information).
