[boost] Re: shared_array: how to get the number of elements in it?

You can always use a shared_ptr to a vector if you need to be able to query the size.

But why could the constructor not be changed from explicit shared_array(T * p = 0); to something like shared_array( T * p, size_t size ); ? I mean, in what situations do we not now the size of the array? br Thorsten
