NAME
       pcap_setfilter - set the filter

SYNOPSIS
       #include <pcap/pcap.h>

       int pcap_setfilter(pcap_t *p, struct bpf_program *fp);

DESCRIPTION
       pcap_setfilter()  is used to specify a filter program.  fp is a pointer
       to  a  bpf_program  struct,  usually  the   result   of   a   call   to
       pcap_compile(3PCAP).

RETURN VALUE
       pcap_setfilter()  returns  0  on  success and PCAP_ERROR on failure. If
       PCAP_ERROR is returned, pcap_geterr(3PCAP) or pcap_perror(3PCAP) may be
       called with p as an argument to fetch or display the error text.
