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().
