The <code class="methodname">DB->stat_print()</code> method displays the
|
||
database statistical information, as described for the
|
||
<a class="xref" href="dbstat.html" title="DB->stat()">DB->stat()</a> 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).
|

|

<p>
|
||
The <code class="methodname">DB->stat_print()</code> method may not be called before the
|
||
<a class="xref" href="dbopen.html" title="DB->open()">DB->open()</a> method is called.

||
</p>
|
||
<p>
|
||
The <code class="methodname">DB->stat_print()</code> <span>
|

<span>
|
||
method returns a non-zero error value on failure and 0 on success.
