NAME
pcap_dump_ftell, pcap_dump_ftell64 - get the current file offset for a savefile being writtenSYNOPSIS
#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(3) and pcap_dump(3). 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.SEE ALSO
