PCAP_OFFLINE_FILTER(3PCAP)                                                        PCAP_OFFLINE_FILTER(3PCAP)



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.

SEE ALSO
       pcap(3PCAP), pcap_compile(3PCAP)
