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(3PCAP).  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.
