[TriLUG] netlink sockets

[John F Davis]

Hello

Does anybody know anything about netlink sockets?  I'm a little confused.
I understand netlink sockets can be used to update the routing table and to
get routing table updates,
but can netlink sockets be used to get interface link messages?  How about
network interface ifconfig up and down notifications?  Also, I want to get
these notifications in user space.
Any idea?
