The point I tried to make is the getaddrinfo function is not sacred. It's not the way to do anything at all on Linux. It's just the function that glibc has, and most people use it. Whether it came from POSIX or something else seems like a minor detail to me. POSIX and glibc are not sacred either.

Linux is no exception. We should all be enjoying those exclusive features to their fullest extent. Not restricting ourselves to the lowest common denominator between them. Portability is a trap.
