Имя (Name)
pcap_fileno - get the file descriptor for a live capture
Синопсис (Synopsis)
#include <pcap/pcap.h>
int pcap_fileno(pcap_t *p);
Описание (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.
