One reason people keep using string manipulation is that in C getaddrinfo gives a addrinfo, which is quite a complex struct. It contains a struct sockaddr, which is actually a sockaddr_in, which contains both an address and a port. So now you have to carefully keep track of which of your addrinfos and sockaddrs have the port in them and which are just the address.
