The <code class="methodname">DbMpoolFile::sync()</code> method writes all modified pages associated with
the <a class="link" href="memp.html" title="Chapter 9.  The DbMpoolFile Handle">DbMpoolFile</a> back to the source file. If any of the
modified pages are <span class="emphasis"><em>pinned</em></span> (that is, currently in use),
<code class="methodname">DbMpoolFile::sync()</code> will ignore them.
</p>
<p>
The <code class="methodname">DbMpoolFile::sync()</code> <span>

method either returns a non-zero error value or throws an
exception that encapsulates a non-zero error value on
failure, and returns 0 on success.
