       struct udev_device
                                                                         *udev_device_get_parent_with_subsystem_devtype(struct udev_device *udev_device,
                                                                         const char *subsystem,
                                                                         const char *devtype);

RETURN VALUE
       On success, udev_device_get_syspath(), udev_device_get_sysname(),
       udev_device_get_sysnum(), udev_device_get_devpath(),
       udev_device_get_devnode(), 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 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.
