_llseek − reposition read/write file offset
#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);
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.
Upon successful completion, _llseek returns 0. Otherwise, a value of −1 is returned and errno is set to indicate the error.

whence is invalid. |
This function is Linux-specific, and should not be used in programs intended to be portable.
The ext2 filesystem does not support files with a size of 2GB or more.
