#include <memory>

template <class X> class auto_ptr;

Description

The template class auto_ptr holds onto a pointer obtained via new and deletes that object when

the auto_ptr object itself is destroyed (such as when leaving block scope). auto_ptr can be used

to make calls to operator new exception-safe. The auto_ptr class provides semantics of strict

ownership: an object may be safely pointed to by only one auto_ptr, so copying an auto_ptr

copies the pointer and transfers ownership to the destination.
