> Maybe things are drastically different on macOS, but getaddrinfo() is the way to resolve names on Linux and I suspect the *BSDs.

I'm not sure if this is the case in this case, but it might be worth noting that some system functions with the same name have drastically different internal/implementation differences between Linux/*BSD/MacOS. With there being differences between the *BSDs too.

So on some systems one function call is "the way", because its been maintained over the years, but then on another it might actually be old and not useful.
