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_com-
       pile().


RETURN VALUE

       pcap_setfilter()  returns  0  on  success  and -1 on failure.  If -1 is
       returned, pcap_geterr() or pcap_perror() may be called  with  p  as  an
       argument to fetch or display the error text.
