NAME

       pcap_fileno - get the file descriptor for a live capture

SYNOPSIS

       #include <pcap/pcap.h>

       int pcap_fileno(pcap_t *p);

DESCRIPTION

       If  p  refers  to  a  network  device  that  was  opened  for  a  live  capture  using  a  combination of
       pcap_create(3PCAP) and pcap_activate(3PCAP), or using pcap_open_live(3PCAP),  pcap_fileno()  returns  the
       file descriptor from which captured packets are read.

       If  p  refers  to  a  ``savefile''  that  was  opened using functions such as pcap_open_offline(3PCAP) or
       pcap_fopen_offline(3PCAP), a ``dead'' pcap_t opened using pcap_open_dead(3PCAP), or  a  pcap_t  that  was
       created  with  pcap_create()  but  that  has  not  yet  been  activated  with pcap_activate(), it returns
       PCAP_ERROR.
