difference_type

template<typename _Ptr , typename _Elt >

using std::__ptr_traits_impl< _Ptr, _Elt >::difference_type = __detected_or_t<ptrdiff_t, __diff_t, _Ptr>

inherited

pointer

template<typename _Ptr , typename _Elt >

using std::__ptr_traits_impl< _Ptr, _Elt >::pointer = _Ptr

inherited

The pointer type.

pointer_to()

template<typename _Ptr , typename _Elt , bool = is_void<_Elt>::value>

static pointer std::__ptr_traits_ptr_to< _Ptr, _Elt, bool >::pointer_to ( element_type &  __r )

inlinestaticinherited

Obtain a pointer to an object.

Parameters

__r	A reference to an object of type element_type

Returns

pointer::pointer_to(__r)

Precondition

pointer::pointer_to(__r) is a valid expression.
