#### General <a id="pointer.traits.general">[[pointer.traits.general]]</a>

The class template `pointer_traits` supplies a uniform interface to
|
| 4 |
+
certain attributes of pointer-like types.

``` cpp
|
| 7 |
+
namespace std {
|
| 8 |
+
template<class Ptr> struct pointer_traits {
|
| 9 |
+
see below;
|
| 10 |
+
};
|
| 11 |
+
|
| 12 |
+
template<class T> struct pointer_traits<T*> {
|
| 13 |
+
using pointer = T*;
|
| 14 |
+
using element_type = T;
|
| 15 |
+
using difference_type = ptrdiff_t;
|
| 16 |
+
|
| 17 |
+
template<class U> using rebind = U*;
|
| 18 |
+
|
| 19 |

static constexpr pointer pointer_to(see below r) noexcept;
|
| 20 |

};

}
