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).
