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