add_pointer

template <class T>
struct add_pointer
{
   typedef see-below type;
};

type: The same type as remove_reference<T>::type*.

The rationale for this template is that it produces the same type as TYPEOF(&t), where t is an object of type T.

C++ Standard Reference: 8.3.1.

Compiler Compatibility: If the compiler does not support partial specialization of class-templates then this template will compile, but the member type will always be the same as type T except where compiler workarounds have been applied.

Header: #include <boost/type_traits/add_pointer.hpp> or #include <boost/type_traits.hpp>
