+<a class="link" href="GUdevClient.html" title="GUdevClient"><span class="type">GUdevClient</span></a> is used to query information about devices on a Linux
+system from the Linux kernel and the udev device
+manager.
+</p>
+<p>
+Device information is retrieved from the kernel (through the
+<code class="literal">sysfs</code> filesystem) and the udev daemon (through a
+<code class="literal">tmpfs</code> filesystem) and presented through
+<a class="link" href="GUdevDevice.html" title="GUdevDevice"><span class="type">GUdevDevice</span></a> objects. This means that no blocking IO ever happens
+(in both cases, we are essentially just reading data from kernel
+memory) and as such there are no asynchronous versions of the
+provided methods.
+</p>
+<p>
+To get <a class="link" href="GUdevDevice.html" title="GUdevDevice"><span class="type">GUdevDevice</span></a> objects, use
