[Olsr-dev] events/notifications for route changes?

[Ian Rose]

Greetings all,

I'm just getting started with OLSR hacking and I'm interested in 
developing a plugin that would receive some kind of notification from 
the OLSR core code whenever a network route is updated (added, deleted, 
changed).  From digging through the code (v0.5.5) I see that there seems 
to be a mechanism by which plugins can register callbacks for when 
network interfaces are added/removed (add_ifchgf and del_ifchgf in 
src/interfaces.h).  But I am unable to find analogous functions to 
registering callbacks for when routes change.  Does such a thing exist?

Obviously I could hack around this by scanning the whole routing table 
every X seconds and looking for differences from the last time I looked, 
but this is rather less appealing to me than a nice simple callback 
mechanism.

thanks very much for any pointers,
