NAME
_llseek - reposition read/write file offset
SYNOPSIS
#include <sys/types.h>
#include <unistd.h>
int _llseek(unsigned int fd, unsigned long offset_high,
unsigned long offset_low, loff_t *result,
unsigned int whence);
Note: There is no glibc wrapper for this system call; see NOTES.
DESCRIPTION
The _llseek() function repositions the offset of the open file associ-
ated with 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 result-
ing 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.
EFAULT Problem with copying results to user space.
EINVAL whence is invalid.
CONFORMING TO
This function is Linux-specific, and should not be used in programs
intended to be portable.
NOTES
Glibc does not provide a wrapper for this system call; call it using
syscall(2).
