returns the standard I/O stream of the ``savefile,'' if a ``savefile''
|
|
|
|
was opened with

|
|
|
or
|
|
|
|
.BR NULL ,
|
|
|
|
if a network device was opened with
|
2023-03-27 18:45:17 +00:00
|
|
|
.BR pcap_create (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

|
|
.BR pcap_file ()
|
2009-03-21 20:43:56 +00:00

|
should, if possible, use calls that support large files on the return
|
|
|
