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 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. PCAP_ERROR is returned on error.
