DESCRIPTION
The _llseek
() function
repositions the offset of the open file associated with the
file descriptor fd
to
(offset_high<<32) |
offset_low bytes relative to the beginning of the
file, the current position in the file, or the end of the
file, depending on whether whence
is SEEK_SET
, SEEK_CUR
, or SEEK_END
, respectively. It returns the
resulting file position in the argument result
.
RETURN VALUE
Upon successful completion, _llseek
() returns 0. Otherwise, a value of
−1 is returned and errno
is set to indicate the error.
ERRORS
- EBADF
-

is not an
open file descriptor.
- EFAULT
