add_volatile Class
Makes volatile type from the specified type.
template<class Ty>
struct add_volatile;
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 volatile-qualified type, otherwise volatile Ty.
Example
// std_tr1__type_traits__add_volatile.cpp
// compile with: /EHsc
#include <type_traits>
#include <iostream>
int main()
{
std::add_volatile<int>::type *p = (volatile int *)0;
p = p; // to quiet "unused" warning
std::cout << "add_volatile<int> == "
<< typeid(*p).name() << std::endl;
return (0);
}
add_volatile<int> == int
