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().
