std::auto_p...atorauto_ptr(3) C++ Standard Libarystd::auto_p...atorauto_ptr(3)

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

Synopsis
	  template< class Y >		      (1) (deprecated in C++11)
	  operator auto_ptr_ref<Y>() throw();	  (removed in C++17)
	  template< class Y >		      (2) (deprecated in C++11)
	  operator auto_ptr<Y>() throw();	  (removed in C++17)

	  Converts *this to an auto_ptr	for a different	type Y.

	  1)  Returns an implementation-defined	type that holds	a reference to
       *this.
	  std::auto_ptr	is convertible and assignable from this	template.  The
       implementation
	  is  allowed  to provide the template with a different	name or	imple-
       ment equivalent
	  functionality	in other ways.
	  2) Constructs	a new auto_ptr with a pointer obtained by calling  re-
       lease().

Parameters
	  (none)

Return value
	  1) An	implementation-defined type that holds a reference to *this
	  2) A auto_ptr	with a pointer obtained	by calling release().

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
       temporaries. 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),
       followed	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.
