<blockquote>
<p><code>closelog</code> closes the current Syslog connection, if there is one.
This includes closing the <samp><span class="file">dev/log</span></samp> socket, if it is open.
<code>closelog</code> also sets the identification string for Syslog messages
back to the default, if <code>openlog</code> was called with a non-NULL argument
to <var>ident</var>. The default identification string is the program name
taken from argv[0].
<p>If you are writing shared library code that uses <code>openlog</code> to
generate custom syslog output, you should use <code>closelog</code> to drop the
GNU C library's internal reference to the <var>ident</var> pointer when you are
done. Please read the section on <code>openlog</code> for more information:
See <a href="openlog.html#openlog">openlog</a>.
<p><code>closelog</code> does not flush any buffers. You do not have to call
<code>closelog</code> before re-opening a Syslog connection with <code>initlog</code>.
Syslog connections are automatically closed on exec or exit.
