- .SH NAME
- pcap_file \- get the standard I/O stream for a savefile being read
- .SH SYNOPSIS
- .nf
- .ft B
- #include <pcap/pcap.h>
- .ft
- .LP
- .ft B
- FILE *pcap_file(pcap_t *p);
- .ft
- .fi
- .SH DESCRIPTION
- .B pcap_file()
- returns the standard I/O stream of the ``savefile,'' if a ``savefile''
- was opened with
- .BR pcap_open_offline() ,
- or NULL, if a network device was opened with
- .B pcap_create()
- and
- .BR pcap_activate() ,
- or with
- .BR pcap_open_live() .
- .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()
- when passed the return value of
- .BR pcap_file() .

- pcap(3PCAP), pcap_open_offline(3PCAP)
