To explain more, a sockaddr_in looks like this:

It shall return 0 if the input is not a valid IPv4 dotted-decimal string or a valid IPv6 address string, or -1 with errno set to [EAFNOSUPPORT] if the af argument is unknown. ERRORS The inet_ntop() and inet_pton() functions shall fail if: EAFNOSUPPORT The af argument is invalid.
