This call retrieves // the IP addresses assigned to the host by interrogating the // kernel. Network applications typically assume // gethostbyname(uname()) will work, but this is just a // convention. It is also problematic if the resolver code // (DNS/NIS+...) is misconfigured. This happens more than // programmers realize. It is better to find out by asking the // kernel for local address assignments. This API is similar to // what netstat -ni or ifconfig -a produces on UNIX or ipconfig on // Windows NT. In fact, it was by reverse engineering these tools // that this api was created. // // = AUTHOR // Michael R.
