PCAP_DUMP_FTELL(3PCAP) PCAP_DUMP_FTELL(3PCAP)
pcap_dump_ftell, pcap_dump_ftell64 - get the current file offset for
a savefile being written
#include <pcap/pcap.h>
long pcap_dump_ftell(pcap_dumper_t *p);
int64_t pcap_dump_ftell64(pcap_dumper_t *p);
pcap_dump_ftell() returns the current file position for the
``savefile'', representing the number of bytes written by
pcap_dump_open() and pcap_dump(). -1 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. -1 is returned on error.
