TITLE : getaddrinfo(), freeaddrinfo(),gai_strerror()
getaddrinfo() is an excellent function that will return information on a particular host name (such as its IP address) and load up a struct sockaddr for you, taking care of the gritty details (like if it's IPv4 or IPv6.) It replaces the old functions gethostbyname() and getservbyname().The description, below, contains a lot of information that might be a little daunting, but actual usage is pretty simple. It might be worth it to check out the examples first........

Lastly, for input parameters, we have hints. This is really where you get to define what the getaddrinfo() function is going to do. Zero the whole structure before use with memset(). Let's take a look at the fields you need to set up before use........

Continuing on with the input paramters, you'll likely want to set ai_family to AF_UNSPEC which tells getaddrinfo() to look for both IPv4 and IPv6 addresses. You can also restrict yourself to one or the other with AF_INET or AF_INET6........
