std::auto_ptr::auto_ptr(3)     C++ Standard Libary    std::auto_ptr::auto_ptr(3)

NAME
     std::auto_ptr::auto_ptr - std::auto_ptr::auto_ptr

Synopsis
	explicit auto_ptr( X* p = 0 ) throw(); (1) (deprecated in C++11)
						   (removed in C++17)
	auto_ptr( auto_ptr& r ) throw();       (2) (deprecated in C++11)
						   (removed in C++17)
	template< class Y >		       (3) (deprecated in C++11)
	auto_ptr( auto_ptr<Y>& r ) throw();	   (removed in C++17)
	auto_ptr( auto_ptr_ref<X> m ) throw(); (4) (deprecated in C++11)
						   (removed in C++17)

	Constructs the auto_ptr from a pointer that refers to the object to man-
     age.

	1) Constructs the auto_ptr with pointer p.
	2)  Constructs	the  auto_ptr with the pointer held in r. r.release() is
     called to
	acquire the ownership of the object.
	3) Same as (2). Y* must be implicitly convertible to T*.
	4) Constructs the auto_ptr with the pointer held  in  the  auto_ptr  in-
     stance referred
	to  by	m.  p.release() is called for the auto_ptr p that m holds to ac-
     quire the
	ownership of the object.
	auto_ptr_ref is an implementation-defined type that holds a reference to
     auto_ptr.
	std::auto_ptr is implicitly convertible  to  and  assignable  from  this
     type. The
	implementation	is allowed to provide the template with a different name
     or implement
	equivalent functionality in other ways.

Parameters
	p - a pointer to an object to manage
	r - another auto_ptr to transfer the ownership of the object from
	m - an implementation-defined type that holds a reference to auto_ptr

Notes
	The constructor and the copy assignment operator  from	auto_ptr_ref  is
     provided to
	allow copy-constructing and assigning std::auto_ptr from nameless tempo-
     raries. Since
	its  copy  constructor and copy assignment operator take the argument as
     non-const
	reference, they cannot bind rvalue arguments directly. However, a  user-
     defined
	conversion  can be executed (which releases the original auto_ptr), fol-
     lowed by a
	call  to  the  constructor  or	copy-assignment   operator   that   take
     auto_ptr_ref by value.
	This is an early implementation of move semantics.
