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

SH DESCRIPTION
BR 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
BR 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
BR pcap_file ()
should, if possible, use calls that support large files on the return
value of
BR pcap_file ()
or the value returned by
BR fileno (3)
when passed the return value of
BR pcap_file ().
