       udev_device_get_devtype(), udev_device_get_subsystem(), udev_device_get_driver() and
       udev_device_get_action() return a pointer to a constant string that describes the
       requested property. 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

       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.
