Subject: [Iftop-users] [PATCH] Cleanup pcap
Message-ID: <1474450197-10981-1-git-send-email-brussell@brocade.com>

Hi,

I'm using iftop with my own libpcap extension which has a 0mq socket
underneath. To exit gracefully, I need to go through pcap_close to
clean up, hence the below patch.

Thanks,

Brian


On exit, call pcap_close() so that any resources used internally
by libpcap can be cleaned up.
