Subject: How do I use ip_conntrack_destroyed?
Date: Wed, 03 Dec 2003 12:17:35 +0200	[thread overview]
Message-ID: <3FCDB83F.3010703@netlab.hut.fi> (raw)


Hei!

I am writing a new target module which needs to be aware about the 
number of conntracks that are currently known for a particular 
destination. Thus, to make my counter I wish to detect when a conntrack 
is destroyed. I have noticed the following in ip_conntrack.h :

/* Call me when a conntrack is destroyed. */
extern void (*ip_conntrack_destroyed)(struct ip_conntrack *conntrack);

So I guess it particularly fits with my needs. But what about using it?

Is it that I have to write something like:
ip_conntrack_destroyed = &my_counter_function
in my ipt_xxxx_target function and then do my stuff in my_counter_funtcion?

Does it work like this?

              Emmanuel
