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