You could look at the ip(8) command source to find out how it is done, /sbin/ip or /bin/ip is part of the iproute package on Red Hat and Debian based Linux distributions.
The ip command uses libnetlink, but there's a new netlink library that is much easier to use. It's called libnl, at http://people.suug.ch/~tgr/libnl/. It includes simple apps that do common things like add routes. Binary packages are available for modern distros.
Latest version of pptp has a hack that uses system(3) to execute ip(8). If you can figure a way to do this without using system(3) then I'm quite interested.
