PCAP_OFFLINE_FILTER(3)                        FreeBSD Library Functions Manual

NAME
       pcap_offline_filter - check whether a filter matches a packet

SYNOPSIS
       #include <pcap/pcap.h>

       int pcap_offline_filter(const 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(3).  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.
