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
returned.
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.
udev_list_entry_get_next(),
udev_list_entry_get_by_name(),
udev_list_entry_get_name(), and
udev_list_entry_get_value() were added in version 221.
