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>

       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  ``save-
       file'',  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.
