add_const

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

type: The same type as T const for all T.

C++ Standard Reference: 3.9.3.

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_const.hpp> or #include <boost/type_traits.hpp>
