SYNOPSIS

       #include <pcap/pcap.h>

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-
