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.
