- * SECTION:gudevdevice
- * @short_description: Get information about a device
- *
- * The #GUdevDevice class is used to get information about a specific
- * device. Note that you cannot instantiate a #GUdevDevice object
- * yourself. Instead you must use #GUdevClient to obtain #GUdevDevice
- * objects.
- *
- * To get basic information about a device, use
- * g_udev_device_get_subsystem(), g_udev_device_get_devtype(),
- * g_udev_device_get_name(), g_udev_device_get_number(),
- * g_udev_device_get_sysfs_path(), g_udev_device_get_driver(),
- * g_udev_device_get_action(), g_udev_device_get_seqnum(),
- * g_udev_device_get_device_type(), g_udev_device_get_device_number(),
- * g_udev_device_get_device_file(),
- * g_udev_device_get_device_file_symlinks().
- *
- * To navigate the device tree, use g_udev_device_get_parent() and
- * g_udev_device_get_parent_with_subsystem().
- *
- * To access udev properties for the device, use
- * g_udev_device_get_property_keys(),
- * g_udev_device_has_property(),
- * g_udev_device_get_property(),
- * g_udev_device_get_property_as_int(),
- * g_udev_device_get_property_as_uint64(),
- * g_udev_device_get_property_as_double(),
- * g_udev_device_get_property_as_boolean() and
- * g_udev_device_get_property_as_strv().
- *
- * To access sysfs attributes for the device, use
- * g_udev_device_get_sysfs_attr_keys(),
- * g_udev_device_has_sysfs_attr(),
- * g_udev_device_get_sysfs_attr(),
- * g_udev_device_get_sysfs_attr_as_int(),
- * g_udev_device_get_sysfs_attr_as_uint64(),
- * g_udev_device_get_sysfs_attr_as_double(),
- * g_udev_device_get_sysfs_attr_as_boolean() and
- * g_udev_device_get_sysfs_attr_as_strv().
- *
- * Note that all getters on #GUdevDevice are non-reffing – returned
- * values are owned by the object, should not be freed and are only
- * valid as long as the object is alive.
- *
- * By design, #GUdevDevice will not react to changes for a device – it
- * only contains a snapshot of information when the #GUdevDevice
- * object was created. To work with changes, you typically connect to
- * the #GUdevClient::uevent signal on a #GUdevClient and get a new
- * #GUdevDevice whenever an event happens.
