Re: [Boost-Users] Why scoped_ptr dost provide custom deallocation?

From: "Black Ice"

As following manner: template<class D> scoped_ptr(Y * p, D d);

Any suggestion are appreciated.

Scoped_ptr is intentionally kept as simple as possible to minimize overhead. A custom deallocation feature as above would require either doubling its size or making its operator* perform a double indirection. If you need the custom deallocator feature, use shared_ptr.
