LLSEEK(2)                  Linux Programmer's Manual                 LLSEEK(2)



NAME
       _llseek - reposition read/write file offset

SYNOPSIS
       #include <unistd.h>

       #include <linux/unistd.h>

       _syscall5(int,  _llseek, uint, fd, ulong, hi, ulong, lo, loff_t *, res,
       uint, wh);

       int _llseek(unsigned int fd, unsigned long offset_high,  unsigned  long
       offset_low, loff_t *result, unsigned int whence);

DESCRIPTION
       The  _llseek  function repositions the offset of 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, respec-
       tively.  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  fd is not an open file descriptor.

       EINVAL whence is invalid.

CONFORMING TO
       This  function  is  Linux-specific,  and should not be used in programs
       intended to be portable.
