RETURN VALUE

27       On success, udev_monitor_filter_update(), udev_monitor_filter_remove(),
28       udev_monitor_filter_add_match_subsystem_devtype() and
29       udev_monitor_filter_add_match_tag() return an integer greater than, or
30       equal to, 0. On failure, a negative error code is returned.
