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}).
