RETURN VALUE         top

       On success, udev_list_entry_get_next() and
       udev_list_entry_get_by_name() return a pointer to the requested
       list entry. If no such entry can be found, or on failure, NULL is

       On success, udev_list_entry_get_name() and
       udev_list_entry_get_value() return a pointer to a constant string
       representing the requested value. The string is bound to the
       lifetime of the list entry itself. On failure, NULL is returned.
