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.
