       8  Compares the first @var{count} bytes of two areas of memory.  Returns
       9  zero if they are the same, nonzero otherwise.  Returns zero if
      10  @var{count} is zero.  A nonzero result only indicates a difference,
      11  it does not indicate any sorting order (say, by having a positive
      12  result mean @var{x} sorts before @var{y}).
