remove_cv Class
The latest version of this topic can be found at remove_cv Class.
Makes non const/volatile type from type.
Syntax
template <class T>
struct remove_cv;
template <class T>
using remove_cv_t = typename remove_cv<T>::type;
Parameters
T
The type to modify.
Remarks
An instance of remove_cv<T>
holds a modified-type that is T1
when T
is of the form const T1
, volatile T1
, or const volatile T1
, otherwise T
.
Example
#include <type_traits>
#include <iostream>
int main()
{
int *p = (std::remove_cv_t<const volatile int> *)0;
p = p; // to quiet "unused" warning
std::cout << "remove_cv_t<const volatile int> == "
<< typeid(*p).name() << std::endl;
return (0);
}
remove_cv_t<const volatile int> == int
