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.
