How about the source code for ifconfig?  [/usr/src/sbin/ifconfig]
It's not simple, because it does a lot of things, but it is the best
example of "ifconfig" type information.

Note that it deals with an IP interface abstraction, not with an
interface card directly.  There can be more (or less) than one address
on an interface.  You need to understand a little better what you are
actually after.
