Overview
pcap_offline_filter() checks whether a filter matches a packet. fp is a pointer to a bpf_program struct, usually the result of a call to pcap_compile(3PCAP). h points to the pcap_pkthdr structure for the packet, and pkt points to the data in the packet.
Return value
pcap_offline_filter() returns the return value of the filter program. This will be zero if the packet doesn't match the filter and non-zero if the packet matches the filter.
