153Note that all getters on <a class="link" href="GUdevDevice.html" title="GUdevDevice"><span class="type">GUdevDevice</span></a> are non-reffing – returned
154values are owned by the object, should not be freed and are only
155valid as long as the object is alive.

158By design, <a class="link" href="GUdevDevice.html" title="GUdevDevice"><span class="type">GUdevDevice</span></a> will not react to changes for a device – it
159only contains a snapshot of information when the <a class="link" href="GUdevDevice.html" title="GUdevDevice"><span class="type">GUdevDevice</span></a>
160object was created. To work with changes, you typically connect to
161the <a class="link" href="GUdevClient.html#GUdevClient-uevent" title='The "uevent" signal'><span class="type">"uevent"</span></a> signal on a <a class="link" href="GUdevClient.html" title="GUdevClient"><span class="type">GUdevClient</span></a> and get a new
162<a class="link" href="GUdevDevice.html" title="GUdevDevice"><span class="type">GUdevDevice</span></a> whenever an event happens.
