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>
pcap_file(3) *p);
DESCRIPTION
pcap_file() returns the standard I/O stream of the ``savefile'', if a
``savefile'' was opened with pcap_open_offline(3), or a null
pointer, if a network device was opened with pcap_create(3) and
pcap_activate(3), or with pcap_open_live(3).
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(3) when passed the
return value of pcap_file().
