pcap_offline_filter - check whether a filter matches a packet
#include <pcap/pcap.h>
int pcap_offline_filter(const struct bpf_program *fp,
const struct pcap_pkthdr *h, const u_char *pkt)
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.
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.
