[Olsr-dev] events/notifications for route changes?
Fri May 23 09:50:04 CEST 2008
pls see olsr_update_kernel_routes() in process_route.c
the post-SPF processing code figures out if there are
-any new routes (add), or
- routes have changed their next-hops (change) or
- routes are unreachable (delete)
and puts the rt_entry into on of the three queues.
all you have to do, is to add callbacks
at the fron of each queue processing fucntion.
