>From bird docs:
You can use the command-line client birdc to talk with a running BIRD. You do 
not necessarily need to use birdc to talk to BIRD, your own applications could 
do that, too.

Now I want to write application, which could get inform/posted when bgp/bfd 
failover, Is there hook or event?
