.SH NAME
|
|
pcap_file \- get the standard I/O stream for a savefile being read
|
|
.SH SYNOPSIS
|
|

|
|
#include <pcap/pcap.h>
|
|

.SH DESCRIPTION
|
|
.B pcap_file()
|
|
returns the standard I/O stream of the ``savefile,'' if a ``savefile''
|
|
was opened with
|
|
.BR pcap_open_offline(3PCAP) ,
|
|
or
|
|
.BR NULL ,
|
|
if a network device was opened with
|
|
.B pcap_create(3PCAP)
|
|
and
|
|
.BR \%pcap_activate(3PCAP) ,
|
|
or with
|
|
.BR pcap_open_live(3PCAP) .
|
|
.PP
|
|
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
|
|
.B pcap_file()
|
|
should, if possible, use calls that support large files on the return
|
|
value of
|
|
.B pcap_file()
|
|
or the value returned by
|
|
.B fileno(3)
|
|
when passed the return value of
|
|
.BR pcap_file() .
