>getaddrinfo_a is available, but not widely adopted (*BSD and Linux), probably because you can't guarantee it'll be available on every computer/phone/modem. This is only an issue if you're targeting POSIX rather than modern operating systems.
To be precise, even on Linux getaddrinfo_a is not guaranteed to be present. It's a glibc extension. musl doesn't have it.
