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_acti-
vate(), it returns PCAP_ERROR.
