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.
