std::experi...al::weak_ptr(3)  C++ Standard Libary std::experi...al::weak_ptr(3)

NAME
     std::experimental::weak_ptr - std::experimental::weak_ptr

Synopsis
	Defined in header <experimental/memory>
	template< class T > class weak_ptr;	 (library fundamentals TS)

	std::experimental::weak_ptr is a modified version of std::weak_ptr that
	interoperates with std::experimental::shared_ptr and has support for ar-
     rays.

Member types
	Member type  Definition
	element_type std::remove_extent_t<T>

Member functions
	constructor   constructs new weak_ptr
		      (public member function)

     Members and non-members identical to std::weak_ptr

Member functions
	The  following	member functions work with std::experimental::shared_ptr
     instead of
	std::shared_ptr    and	  std::experimental::weak_ptr	  instead     of
     std::weak_ptr. The
	behavior is otherwise identical.

	destructor   destroys a weak_ptr
		     (public member function of std::weak_ptr<T>)
	operator=    assigns the weak_ptr
		     (public member function of std::weak_ptr<T>)

Modifiers
	reset	     releases the ownership of the managed object
		     (public member function of std::weak_ptr<T>)
	swap	     swaps the managed objects
		     (public member function of std::weak_ptr<T>)

Observers
	use_count     returns  the  number of shared_ptr objects that manage the
     object
		     (public member function of std::weak_ptr<T>)
	expired      checks whether the referenced object was already deleted
		     (public member function of std::weak_ptr<T>)
	lock	     creates a shared_ptr that manages the referenced object
		     (public member function of std::weak_ptr<T>)
	owner_before provides owner-based ordering of weak pointers
		     (public member function of std::weak_ptr<T>)

Non-member functions
	This non-member function is declared in the std::experimental namespace,
     and work
	with std::experimental::weak_ptr rather than std::weak_ptr,  but  other-
     wise behaves
	identically to the corresponding C++14 function.

	std::swap(std::weak_ptr) specializes the std::swap algorithm
	(C++11) 		 (function template)
