PCAP_DUMP_FTELL

NAME
pcap_dump_ftell, pcap_dump_ftell64 - get the current file offset for a savefile being written
SYNOPSIS
#include <pcap/pcap.h>
long pcap_dump_ftell(pcap_dumper_t *p);
int64_t pcap_dump_ftell64(pcap_dumper_t *p);
DESCRIPTION
pcap_dump_ftell()
returns the current file position for the ``savefile'', representing the
number of bytes written by
pcap_dump_open(3PCAP)
and
pcap_dump(3PCAP).
PCAP_ERROR
is returned on error. If the current file position does not fit in a
long,
it will be truncated; this can happen on 3-bit UNI-like systems with
large file support and on Windows.
pcap_dump_ftell64()
returns the current file position in a
int64_t,
so if file offsets that don't fit in a
long
but that fit in a
int64_t
are supported, this will return the file offset without truncation.
PCAP_ERROR
is returned on error.
BACKWARD COMPATIBILITY
The function
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
long.
