The lifetime of this string is bound to the device it was requested on. On failure, each function may return NULL. On success, udev_device_get_devnum() returns the device type of the passed device. On failure, a device type with minor and major number set to 0 is returned. udev_device_get_udev() always returns a valid pointer to the udev context that this device belongs to. On success, udev_device_get_parent() and udev_device_get_parent_with_subsystem_devtype() return a pointer to the parent device. No additional reference to this device is acquired, but the child device owns a reference to such a parent device. On failure, NULL is returned. On success, udev_device_get_is_initialized() returns either 1 or 0, depending on whether the passed device has already been initialized by udev or not. On failure, a negative error code is returned. Note that devices for which no udev rules are defined are never reported initialized. udev_new3, udev_device_new_from_syspath3, udev_device_has_tag3, udev_enumerate_new3, udev_monitor_new_from_netlink3, udev_list_entry3, systemd1
