15 pcap_offline_filter() checks whether a filter matches a packet. fp is
16 a pointer to a bpf_program struct, usually the result of a call to
17 pcap_compile(). h points to the pcap_pkthdr structure for the packet,
18 and pkt points to the data in the packet.

21 pcap_offline_filter() returns the return value of the filter program.
22 This will be zero if the packet doesn't match the filter and non-zero
23 if the packet matches the filter.
