_llseek

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,
       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  fd is not an open file descriptor.

       EINVAL whence is invalid.

       EFAULT Problem with copying results to user space.

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