PCAP_FILENO(3PCAP)                                                                        PCAP_FILENO(3PCAP)



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_cre-ate() pcap_create()
       ate() 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.
