28<b>Description: DbMpoolFile::sync</b>
29<p>The DbMpoolFile::sync method writes all modified pages associated with the
30<a href="/api_cxx/mempfile_class.html">DbMpoolFile</a> back to the source file.  If any of the modified
31pages are <i>pinned</i> (that is, currently in use),
32DbMpoolFile::sync will ignore them.</p>
33<p>The DbMpoolFile::sync method
34either returns a non-zero error value
35or throws an exception that encapsulates a non-zero error value on
36failure, and returns 0 on success.
