.SH NAME
|
|
pcap_dump_ftell, pcap_dump_ftell64 \- get the current file offset for a savefile being written
|

.SH DESCRIPTION
|
|
.BR pcap_dump_ftell ()
|
|
returns the current file position for the ``savefile'', representing the
|
|
number of bytes written by
|
|
.BR pcap_dump_open (3PCAP)
|
|
and
|
|
.BR pcap_dump (3PCAP).
|
|
.B PCAP_ERROR
|
|
is returned on error. If the current file position does not fit in a
|
|
.BR long ,
|
|
it will be truncated; this can happen on 32-bit UNIX-like systems with
|
|
large file support and on Windows.
|
|
.BR pcap_dump_ftell64 ()
|
|
returns the current file position in a
|
|
.BR int64_t ,
|
|
so if file offsets that don't fit in a
|
|
.B long
|
|
but that fit in a
|
|
.B int64_t
|
|
are supported, this will return the file offset without truncation.
|
|
.B PCAP_ERROR
|
|
is returned on error.
|
|
.SH BACKWARD COMPATIBILITY
|
|
The function
|
|
.BR pcap_dump_ftell64 ()
|
|
became available in libpcap release 1.9.0. In previous releases, there
|
|
was no mechanism to obtain a file offset that is too large to fit in a
|
|
.BR long .
