<h1>Daemon</h1>

<h2>Command Line Arguments</h2>

The <tt>polypaudio</tt> daemon accepts several command line arguments:

<p><tt>-L MODULE</tt>: Load the specified module. This option may be specified more than once.</p>
<p><tt>-F FILE</tt>: Run the specified script. This option may be specified more than once.</p>
<p><tt>-C</tt>: Load the module <a href="modules.html#module-cli"><tt>module-cli</tt></a> after startup.</p>
<p><tt>-D</tt>: Daemonize after successfully executing all scripts and loading all modules.</p>
<p><tt>-f</tt>: Unless this option is given the daemon will terminate if any of the specified modules failed to load or the script didn't execute successfully.</p>
<p><tt>-v</tt>: Increase the verbosity of the daemon.</p>
<p><tt>-h</tt>: Show a quick help.</p>

<h3>Example</h3>

<p>It is a good idea to run the daemon like this:</p>

<pre>polypaudio -D -F /etc/polypaudio/polypaudio.pa</pre>

<p><tt>/etc/polypaudio/polypaudio.pa</tt> should be a script written in the CLI language described in <a href="cli.html">cli.html</a>

<h2>Signals</h2>

<p>The following signals are trapped specially:</p>

<h3>SIGINT</h3>

<p>The daemon is shut down cleanly.</p>

<h3>SIGUSR1</h3>

<p>The daemon tries to load the module <a href="modules.html#module-cli"><tt>module-cli</tt></a>, effectively providing a command line interface on the calling TTY.</p>

<h3>SIGUSR2</h3>

<p>The daemon tries to load the module <a href="modules.html#module-cli-protocol-unix"><tt>module-cli-protocol-unix</tt></a>, effectively providing a command line interface on a special UNIX domain socket.</p>
