pcap_dump_ftell(3) pcap_dump_ftell(3)
NAME
pcap_dump_ftell, pcap_dump_ftell64 - get the current file offset for a
savefile being written
SYNOPSIS
#include <pcap/pcap.h>
pcap_dump_ftell(3) *p);
int64_t pcap_dump_ftell64(pcap_dumper_t *p);
DESCRIPTION
pcap_dump_ftell(3) returns the current file position for the ``save-
file'', representing the number of bytes written by pcap_dump_open()
and pcap_dump(). -1 is returned on error. If the current file posi-
tion does not fit in a long, it will be truncated; this can happen on
32-bit UNIX-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. -1 is
returned on error.
