.SH DESCRIPTION
|
|
|
|
|
.B pcap_file()
|
|
|
|
|
returns the standard I/O stream of the ``savefile,'' if a ``savefile''
|
|
|
|
|
was opened with
|
2019-10-06 04:26:37 +00:00
|
|
|
.BR pcap_open_offline(3PCAP) ,
|
|
|
|
|
or
|
|
|
|
|
.BR NULL ,
|
|
|
|
|
if a network device was opened with
|
|
|
|
|
.B pcap_create(3PCAP)
|
2009-03-21 20:43:56 +00:00
|
|
|
and
|
2019-10-06 04:26:37 +00:00
|
|
|
.BR \%pcap_activate(3PCAP) ,
|
2009-03-21 20:43:56 +00:00
|
|
|
or with
|
2019-10-06 04:26:37 +00:00
|

.BR 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
|
|
|
|
|
.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
|
2019-10-06 04:26:37 +00:00
|
|
|
.B fileno(3)
|
2009-03-21 20:43:56 +00:00
|
|
|
when passed the return value of
|
