<h3><pre>
#include <db.h>

int
DB_MPOOLFILE->close(DB_MPOOLFILE *mpf, u_int32_t flags);
</pre></h3>
<h1>Description</h1>
<p>The DB_MPOOLFILE->close method closes the source file indicated by the
<a href="../api_c/mempfile_class.html">DB_MPOOLFILE</a> structure. Calling DB_MPOOLFILE->close does not imply a call
to <a href="../api_c/memp_fsync.html">DB_MPOOLFILE->sync</a>; that is, no pages are written to the source file
as as a result of calling DB_MPOOLFILE->close.
<p>If the <a href="../api_c/mempfile_class.html">DB_MPOOLFILE</a> was temporary, any underlying files created
for this <a href="../api_c/mempfile_class.html">DB_MPOOLFILE</a> will be removed.
<p>The <b>flags</b> parameter is currently unused, and must be set to 0.
<p>After DB_MPOOLFILE->close has been called, regardless of its return, the
<a href="../api_c/mempfile_class.html">DB_MPOOLFILE</a> handle may not be accessed again.
<p>The DB_MPOOLFILE->close method returns a non-zero error value on failure and 0 on success.
<h1>Errors</h1>
<p>The DB_MPOOLFILE->close method may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
If a catastrophic error has occurred, the DB_MPOOLFILE->close method may fail and
return <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>,
in which case all subsequent Berkeley DB calls will fail in the same way.
