+/**
+ * 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.

+ * 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(),
+ * 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.

+ * DISCLAIMER - The file format mentioned here is private to udev/libudev,
+ * and may be changed without notice.
+ *
+ * The udev event queue is exported as a binary log file.
+ * Each log record consists of a sequence number followed by the device path.
+ *
+ * When a new event is queued, its details are appended to the log.
+ * When the event finishes, a second record is appended to the log
+ * with the same sequence number but a devpath len of 0.
+ *
+ * Example:
+ * { 0x0000000000000001 }
+ * { 0x0000000000000001, 0x0019, "/devices/virtual/mem/null" },
+ * { 0x0000000000000002, 0x001b, "/devices/virtual/mem/random" },
+ * { 0x0000000000000001, 0x0000 },
+ * { 0x0000000000000003, 0x0019, "/devices/virtual/mem/zero" },
+ *
+ * Events 2 and 3 are still queued, but event 1 has finished.
+ *
+ * The queue does not grow indefinitely. It is periodically re-created
+ * to remove finished events. Atomic rename() makes this transparent to readers.
+ *
+ * The queue file starts with a single sequence number which specifies the
+ * minimum sequence number in the log that follows. Any events prior to this
+ * sequence number have already finished.

- * 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.

- * 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(),
- * 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.

- * DISCLAIMER - The file format mentioned here is private to udev/libudev,
- * and may be changed without notice.
- *
- * The udev event queue is exported as a binary log file.
- * Each log record consists of a sequence number followed by the device path.
- *
- * When a new event is queued, its details are appended to the log.
- * When the event finishes, a second record is appended to the log
- * with the same sequence number but a devpath len of 0.
- *
- * Example:
- * { 0x0000000000000001 }
- * { 0x0000000000000001, 0x0019, "/devices/virtual/mem/null" },
- * { 0x0000000000000002, 0x001b, "/devices/virtual/mem/random" },
- * { 0x0000000000000001, 0x0000 },
- * { 0x0000000000000003, 0x0019, "/devices/virtual/mem/zero" },
- *
- * Events 2 and 3 are still queued, but event 1 has finished.
- *
- * The queue does not grow indefinitely. It is periodically re-created
- * to remove finished events. Atomic rename() makes this transparent to readers.
- *
- * The queue file starts with a single sequence number which specifies the
- * minimum sequence number in the log that follows. Any events prior to this
- * sequence number have already finished.
