Generally sockaddr alone for this kind of purpose is frowned on in my
view since there is no portable way to get the address length, and all
downstream functions require the length..

The best interface is something like getaddrinfo that returns a new
type that has the family, address and length in the structure.

Also, your second version would require the address array to be of
type sockaddr_storage, since sockaddr can only point to, not store
addresses..
