- * SECTION:gudevclient
- * @short_description: Query devices and listen to uevents
- *
- * #GUdevClient is used to query information about devices on a Linux
- * system from the Linux kernel and the udev device
- * manager.
- *
- * Device information is retrieved from the kernel (through the
- * <literal>sysfs</literal> filesystem) and the udev daemon (through a
- * <literal>tmpfs</literal> filesystem) and presented through
- * #GUdevDevice 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.
- *
- * To get #GUdevDevice objects, use
- * g_udev_client_query_by_subsystem(),
- * g_udev_client_query_by_device_number(),
- * g_udev_client_query_by_device_file(),
- * g_udev_client_query_by_sysfs_path(),
- * g_udev_client_query_by_subsystem_and_name()
- * or the #GUdevEnumerator type.
- *
- * To listen to uevents, connect to the #GUdevClient::uevent signal.
