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 us-
       ing a  combination  of  pcap_create()  and  pcap_activate(),  or	 using
       pcap_open_live(),  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()  or	pcap_fopen_offline(), a	``dead'' pcap_t	opened
       using pcap_open_dead(), or a pcap_t that	was created with pcap_create()
       but  that  has  not yet been activated with pcap_activate(), it returns
       -1.
