получить текущее смещение файла для записываемого файла сохранения (get the current file offset for a savefile being written)
Имя (Name)
pcap_dump_ftell, pcap_dump_ftell64 - get the current file offset
for a savefile being written
Синопсис (Synopsis)
#include <pcap/pcap.h>
long pcap_dump_ftell(pcap_dumper_t *p);
int64_t pcap_dump_ftell64(pcap_dumper_t *p);
Описание (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 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.
Обратная совместимость (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.
