       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.

       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.

       This system call exists on various 32-bit platforms to support  seeking
       to large file offsets.

       Upon successful completion, _llseek() returns 0.  Otherwise, a value of
       -1 is returned and errno is set to indicate the error.

       EBADF  fd is not an open file descriptor.

       EFAULT Problem with copying results to user space.

       EINVAL whence is invalid.

       This function is Linux-specific, and should not  be  used  in  programs
       intended to be portable.

       Glibc  does  not  provide a wrapper for this system call.  To invoke it
       directly, use syscall(2).   However,  you  probably  want  to  use  the
       lseek(2) wrapper function instead.
