NAME

SYNOPSIS

11       FILE *pcap_file(pcap_t *p);

DESCRIPTION

14       pcap_file()  returns  the standard I/O stream of the ``savefile,'' if a
15       ``savefile'' was opened with pcap_open_offline(3PCAP), or  NULL,  if  a
16       network    device    was    opened    with    pcap_create(3PCAP)    and
17       pcap_activate(3PCAP), or with pcap_open_live(3PCAP).
18
19       Note that the Packet Capture library is usually built with  large  file
20       support,  so the standard I/O stream of the ``savefile'' might refer to
21       a file larger than  2  gigabytes;  applications  that  use  pcap_file()
22       should,  if  possible, use calls that support large files on the return
23       value of pcap_file() or the value returned by fileno(3) when passed the
24       return value of pcap_file().
