add_const Class

Makes const type from type.

template<class Ty>
    struct add_const;

Parameters

• Ty
  The type to modify.

Remarks

An instance of the type modifier holds a modified-type that is Ty if Ty is a reference, a function, or a const-qualified type, otherwise const Ty.

Example

// std_tr1__type_traits__add_const.cpp 
// compile with: /EHsc 
#include <type_traits> 
#include <iostream> 
 
int main() 
    { 
    std::add_const<int>::type *p = (const int *)0; 
 
    p = p;  // to quiet "unused" warning 
    std::cout << "add_const<int> == " 
        << typeid(*p).name() << std::endl; 
 
    return (0); 
    } 
 

add_const<int> == int
