template< class T > void swap( shared_ptr<T>& lhs, shared_ptr<T>& rhs ) noexcept;		(since C++11)

Specializes the std::swap algorithm for std::shared_ptr. Swaps the pointers of lhs and rhs. Calls lhs.swap(rhs).

Parameters

lhs, rhs

-

smart pointers whose contents to swap

Return value

(none)

Complexity

Constant
