<h3 class="section">23.5 Giving information about a plugin</h3>

<p>A plugin should give some information to the user about itself. This
uses the following structure:
</p>
<div class="smallexample">
<pre class="smallexample">struct plugin_info
{
  const char *version;
  const char *help;
};
</pre></div>

<p>Such a structure is passed as the <code>user_data</code> by the plugin&rsquo;s
init routine using <code>register_callback</code> with the
<code>PLUGIN_INFO</code> pseudo-event and a null callback.
</p>
