well, "new" as in about 16 years old.
Yes, all of us returning more than one A / AAAA record are hoping that gets widely deployed instantly. Or not.
inet_addr() is zomfg brain damaged, ipv4 only, non-thread-safe and needs to die horribly in a fire. getaddrinfo() puts at least the possibility of address selection into the hands of the developer which is going to be completely necessary for happy eyeballs / rfc3484bis / etc. Nick
