Simple question on ip address monitoring

[Manthei, Mark]

I have a simple use case but I still haven't found how to accomplish this:

I want to loop through all known interface cards and collect information.
I have figured out how to get basic info (interface name, MAC address) but I am unable to get the IP address.

I thought the following would obtain the IP but appears to get the MAC address:

                     // now do ip address stuff with address cache
                        struct rtnl_link *pAddrLink = rtnl_link_get( pLinkCache, idx );
                        if(pAddrLink)
                        {
                           addr = rtnl_link_get_addr(pAddrLink);
                           int addressguess = nl_addr_guess_family(addr);
                           std::cout << "addr2 guess: " << addressguess << std::endl;



                           nl_addr2str( addr,  buf,  128 );
                           std::cout << " ipaddress: " << buf << std::endl;
                        }


Is there an example I'm missing that might shed some light on how to accomplish this?

Thanks
