|   template< class Y > 
auto_ptr& operator=( auto_ptr<Y>& r );  |

|   template< class Y >

(2) | (deprecated) | 
Replaces the managed object with the one managed by r. 
1) Effectively calls reset(r.release()). 
2) Effectively calls reset(r.release()). Y* must be implicitly convertible to T*.
3) Effectively calls reset(m.release()). 
auto_ptr_ref is an implementation-defined type that holds a reference to auto_ptr. The implementation is allowed to provide the template with a different name or implement equivalent functionality in other ways.[edit] Parameters
| r | - |   another auto_ptr to transfer the ownership of the object from
 | 
| m | - |   an implementation-defined type that holds a reference to auto_ptr
 | 
[edit] Return value
*this.
