Is it possible to register for callbacks so that a user application is

No, update to packet/byte count doesn't trigger an event (it would
trigger too often).
I was hoping if there was an option to set a timeout, so that an update
would trigger every 5 seconds for flows where the counters have changed.
I can poll the stats using something similar to "conntrack -L". However, I
was wondering if it's possible to be notified regularly on updates.
No. What semantics would you be interested in?
Dumping is quite fast, whats the problem you need to solve?
I have an application that needs to keep track of per flow stats for all
tcp flows destined to port 80. The best way I have found so far is to
call nfct_query regularly and to go through each flow returned to
retrieve the counters. Would that be the best way to do it?
Thank you for your assistance.
