NAME
       pcap_offline_filter - check whether a filter matches a packet

SYNOPSIS
       #include <pcap/pcap.h>

       int pcap_offline_filter(struct bpf_program *fp,
	       const struct pcap_pkthdr *h, const u_char *pkt)

DESCRIPTION
       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().   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.
