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.

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);

DESCRIPTION

       The  _llseek()  function  repositions  the offset of the open file associated 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 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.

       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).
