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

NAME
     std::owner_less - std::owner_less

Synopsis
	Defined in header <memory>
	template<>		    (since C++17)
	struct owner_less<void>;

	std::owner_less<void>  is a specialization of std::owner_less with para-
     meter types
	deduced.

Member functions
	operator() compares its arguments using owner-based semantics
		   (function)

     std::owner_less<void>::operator()

	template< class T, class U >

	bool operator()( const std::shared_ptr<T>& lhs, 		  (since
     C++17)

			 const std::shared_ptr<U>& rhs ) const noexcept;
	template< class T, class U >

	bool operator()( const std::shared_ptr<T>& lhs, 		  (since
     C++17)

			 const std::weak_ptr<U>& rhs ) const noexcept;
	template< class T, class U >

	bool operator()( const std::weak_ptr<T>& lhs,			  (since
     C++17)

			 const std::shared_ptr<U>& rhs ) const noexcept;
	template< class T, class U >

	bool operator()( const std::weak_ptr<T>& lhs,			  (since
     C++17)

			 const std::weak_ptr<U>& rhs ) const noexcept;

	Compares lhs and rhs using owner-based semantics. Effectively calls
	lhs.owner_before(rhs).

	The ordering is strict weak ordering relation.

	lhs and rhs are equivalent only if they are both empty or  share  owner-
     ship.

Parameters
	lhs, rhs - shared-ownership pointers to compare

Return value
	true if lhs is less than rhs as determined by the owner-based ordering.
