Adds a subgroup to another group.
- macOS 10.2+
The group you wish to add a subgroup to. If
NULL, this function raises an exception.
The subgroup you wish to add to
successful. If the
is already part of the receiver, this function does nothing and
false. If adding the group would
create a recursion, this function also does nothing and returns
example, if the group “Animal Lovers” is in “Dog Lovers,”
and you add “Dog Lovers” to “Animal Lovers,” that would
create a recursion, which this function won’t allow.
