NAME
       std::pointer_traits< _Ptr > - Uniform interface to all pointer-like
       types.


SYNOPSIS
       #include <memory>

       Inherits std::__ptr_traits_impl< _Ptr, _Elt >.

   Public Types
       using difference_type
           The type used to represent the difference between two pointers.
       using element_type
           The type pointed to.
       using pointer
           The pointer type.
       template<typename _Up > using rebind
           A pointer to a different type.

   Static Public Member Functions
       static pointer pointer_to (element_type &__r)
           Obtain a pointer to an object.

Member Typedef Documentation
   template<typename _Ptr , typename _Elt > using std::__ptr_traits_impl<
       _Ptr, _Elt >::difference_type [inherited]
       The type used to represent the difference between two pointers.

   template<typename _Ptr , typename _Elt > using std::__ptr_traits_impl<
       _Ptr, _Elt >::element_type [inherited]
       The type pointed to.

   template<typename _Ptr , typename _Elt > using std::__ptr_traits_impl<
       _Ptr, _Elt >::pointer [inherited]
       The pointer type.

   template<typename _Ptr , typename _Elt > template<typename _Up > using
       std::__ptr_traits_impl< _Ptr, _Elt >::rebind [inherited]
       A pointer to a different type.

Member Function Documentation
   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) [inline],  [static],  [inherited]
       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.
