shared_ptr::operator->

Gets a pointer to the designated value.

Ty *operator->() const;

The selection operator returns get(), so that the expression sp->member behaves the same as (sp.get())->member where sp is an object of class shared_ptr<Ty>. Hence, the stored pointer must not be null, and Ty must be a class, structure, or union type with a member member.
