Look for iproute2 sources.. Excellent stuff.. I guess the sourceforge-ldp
is also doing that.

I will explain the basic idea.
create a netlink socket, bind it to a multicast group of all netlink
messages. (Binding it to routing message group is also suffice.)

Listen on this netlink socket for any messages delievered by
kernel.

Decode and use the info. Look at the sources above would help u in using
them
