<h1>DbMpoolFile::close</h1>

<h1>Description</h1>
<p>
The DbMpoolFile::close method closes the source file indicated by the
<a href="../../api_cxx/DbMpoolFile/class.html">DbMpoolFile</a> object. Calling DbMpoolFile::close does not imply
a call to <a href="../../api_cxx/DbMpoolFile/sync.html">DbMpoolFile::sync</a>, i.e. no pages are written to the source
file as as a result of calling DbMpoolFile::close.
<p>
In addition, if the <b>file</b> argument to <a href="../../api_cxx/DbMpoolFile/open.html">DbMpoolFile::open</a> was NULL,
any underlying files created for this <a href="../../api_cxx/DbMpoolFile/class.html">DbMpoolFile</a> will be removed.
<p>
The DbMpoolFile::close
method either returns <b>errno</b> or throws an exception that
encapsulates an <b>errno</b> on failure, and 0 on success.
<p>
<h1>Errors</h1>
If a fatal error occurs in Berkeley DB, the DbMpoolFile::close method may fail and either
return DB_RUNRECOVERY or throw an exception encapsulating DB_RUNRECOVERY,
at which point all subsequent database calls will also fail in the same
way. Methods marked as returning <b>errno</b> will, by default, throw
an exception that encapsulates the error information. The default error
behavior can be changed, see <a href="../../api_cxx/DbException/class.html">DbException</a>.
<p>
The DbMpoolFile::close
method may fail and throw an exception
for any of the errors specified for the following Berkeley DB and C library
functions:
abort(3),
close(3),
fcntl(3),
fflush(3),
fprintf(3),
free(3),
getpid(3),
memset(3),
munmap(3),
strerror(3),
vfprintf(3),
and
vsnprintf(3).
