<h1> The <tt>mdevd-coldplug</tt> program </h1>
<p>
<tt>mdevd-coldplug</tt> performs a <em>coldplug</em>: it scans
<tt>/sys</tt> for all registered devices a uevent manager would
want to perform actions on, and tells the kernel to generate uevents
for all these devices.
</p>
<h2> Interface </h2>
<pre>
mdevd-coldplug [ -s <em>slashsys</em> ]
</pre>
<ul>
<li> mdevd-coldplug scans <tt>/sys</tt> for devices. </li>
<li> For every suitable device it finds, it tells the kernel
to generate an event. If a device manager such as
as <a href="mdevd.html">mdevd</a> is listening to the netlink
at this point, it will pick up the series of events. </li>
<li> mdevd-coldplug exits when it has finished scanning. </li>
</ul>
<h2> Options </h2>
<ul>
<li> <tt>-s</tt> <em>slashsys</em> : assume the sysfs
pseudo-filesystem is mounted on <em>slashsys</em>. Default is <tt>/sys</tt>. </li>
</ul>
<h2> Exit codes </h2>
<ul>
<li> 0: success </li>
<li> 111: system call failed </li>
</ul>
<h2> Notes </h2>
<ul>
<li> mdevd-coldplug is a short-lived program, just like
<tt>mdev -s</tt> or <tt>udevadm trigger</tt>. </li>
</ul>
