Section (3) fseeko
fseeko, ftello — seek to or report file position
ftello() functions are
identical to fseek(3) and ftell(3) (see fseek(3)), respectively,
except that the
offset argument of
fseeko() and the return value of
ftello() is of type
off_t instead of long.
On some architectures, both off_t and long are
32-bit types, but defining
_FILE_OFFSET_BITS with the value 64 (before
any header files)
will turn off_t into a 64-bit
On successful completion,
fseeko() returns 0, while
ftello() returns the current offset.
Otherwise, −1 is returned and
errno is set to indicate the error.
See the ERRORS in fseek(3).
