Re: [Boost-users] Boost-users Digest, Vol 1945, Issue 2

but in this case array_size is re-assigned after p_array was allocated, thus not reflecting the size of the allocated buffer;

The order of initialization is following: 1) Base::size 2) Base::p_array So the array is allocated after the size is assigned.

I need some dynamically allocated space that can later be casted to C pointers,  so that it can be passed to a Win32 API function that accepts C pointers only. vectors are dynamic, but they don't cast to C arrays naturally.

std::vector provides the guarantee that its elements are in contigous memory block, so &*vec.begin() is a ptr to c-like array.
