Generally true. As a minor caveat, I would mention that getaddrinfo() in
the most recent glibc applies an ill-advised sorting rule (RFC 3484 section
6, rule 9) to IPv4 addresses which breaks the expected round-robin behavior
of gethostby* for no particular benefit (the addresses are sorted by length
of prefix match, which doesn't at all map to how the Internet is put
So at present, migrating to getaddrinfo() is not entirely without tradeoffs.
Steve Langasek Give me a lever long enough and a Free OS
Debian Developer to set it on, and I can move the world.
