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()
       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.
