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.
