static pointer pointer_to( element_type& r ) noexcept;
|(2)|| (since C++11)
Constructs a dereferenceable pointer or pointer-like object ("fancy pointer") to its argument.
1) The version of this function in the non-specialized std::pointer_traits template simply calls Ptr::pointer_to(r), and if Ptr does not provide a static member function
pointer_to, instantiation of this function is a compile-time error.
2) The version of this function in the specialization of std::pointer_traits for pointer types returns std::addressof(r)
|r||-|| reference to an object of type element_type&, except if element_type is void, in which case the type of |
 Return value
A dereferenceable pointer to
r, of the type pointer_traits<>::pointer.
1) Unspecified (typically same as Ptr::pointer_to)
