PCAP_FILE(3PCAP) PCAP_FILE(3PCAP)
pcap_file - get the standard I/O stream for a savefile being read
#include <pcap/pcap.h>
FILE *pcap_file(pcap_t *p);
pcap_file() returns the standard I/O stream of the ``savefile,''
if a ``savefile'' was opened with pcap_open_offline(3PCAP), or
NULL, if a network device was opened with pcap_create(3PCAP) and
pcap_activate(3PCAP), or with pcap_open_live(3PCAP).
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().
