Hi,

I am trying to use libpcap to read packets from a
trace file generated using tcpdump -w

Just want to confirm if the following set of calls is
sufficient: 

pcap_open_offline()
pcap_compile()
pcap_setfilter()
pcap_dispatch()

Since this is a trace file and not a live capture,
what value should I use for the subnetmask argument
required by pcap_compile.

Please also let me know of any other gotchas.

Thanks,
Joe
