Explicitly calling a constructor
Author
How can I explicitly call the constructor for a class?
You should be using placement new, which will not actually allocate the object, just construct one at the address you give.
Edit: One restriction I didn't know of is that the memory you construct it in has to be allocated on the heap.

Ohhhh, I didn't know you could do that...[smile]

That sounds what I was looking for, thanks a bunch. Btw, the memory is allocated on the heap for a pooled memory manager.
