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.
