39 * A wrapper class to provide auto_ptr with reference semantics.
40 * For example, an auto_ptr can be assigned (or constructed from)
41 * the result of a function which returns an auto_ptr by value.
60 * An @c auto_ptr owns the object it holds a pointer to. Copying
61 * an @c auto_ptr copies the pointer and transfers ownership to the
62 * destination. If more than one @c auto_ptr owns the same object
65 * The uses of @c auto_ptr include providing temporary
69 * auto_ptr does not meet the CopyConstructible and Assignable
72 * instantiating a Standard Library container with an @c auto_ptr
77 * Good examples of what can and cannot be done with auto_ptr can
81 * 127. auto_ptr<> conversion issues
