There is. It's called shared_ptr.

This is not the end of story, however. For example, a factory that creates
an object on the heap and transfers ownership to the user should return an
auto_ptr, not a shared_ptr. Similarly, a function that returns a pointer to
an object derived from counted_base should return an intrusive_ptr, not
shared_ptr. This is not an interoperability problem since both can be
converted to a shared_ptr; it's "as if" a shared_ptr is being returned.
