PCAP_FILE(3) PCAP_FILE(3)
NAME
pcap_file - get the standard I/O stream for a savefile being read
SYNOPSIS
#include <pcap/pcap.h>
FILE *pcap_file(pcap_t *p);
DESCRIPTION
pcap_file() returns the standard I/O stream of the ``savefile,'' if a
``savefile'' was opened with pcap_open_offline(), or NULL, if a network
device was opened with pcap_create() and pcap_activate(), or with
pcap_open_live().
Note that the Packet Capture library is usually built with large file
support, so the standard I/O stream of the ``savefile'' might refer to
a file larger than 2 gigabytes; applications that use pcap_file()
should, if possible, use calls that support large files on the return
value of pcap_file() or the value returned by fileno() when passed the
return value of pcap_file().
