<hr><a name="_details"></a><h2>Detailed Description</h2>
The slog class is used to stream messages to the system logging fascility. system logging fascility class.
<p>
A default <code>slog</code> object is used to avoid confusion with the native syslog fascility and to imply a logical relationship to the C++ <code>clog()</code>.
<p>
The key difference is that the <code>slog</code> object sends it's output to the system logging daemon (typically syslogd) rather than through stderr. <code>slog</code> can be streamed with the <code><<</code> operator just like <code>clog</code>; a default slog object is pre-initialized, and you stream character data to it.
<p>
The <code>slog</code> allows one to specify logging levels and other properties through the <code>()</code> operators. Hence, once can do:
<p>
<code><pre>
slog("mydaemon", SLOG_DAEMON, SLOG_EMERGENCY) << I just died << endl; </pre></code>
<p>
or things like:
<p>
<code><pre>
slog("mydaemon", SLOG_DAEMON);
slog(SLOG_INFO) << "daemon initalized" << endl; </pre></code>
<p>
The intent is to be as common-place and as convenient to use as the stderr based clog facility found in C++, and this is especially useful for C++ daemons.
