memmove C++ -> D

[Clay Smith]

C++ memmove:

memmove(bounds + upperIndex + 2, bounds + upperIndex, (edgeCount - 
upperIndex) * sizeof(b2Bound));

D memmove:

memmove(bounds.ptr + upperIndex + 2, bounds.ptr + upperIndex, (edgeCount 
- upperIndex) * b2Bound.sizeof);

Is this a correct translation to D? Thanks.
