この実装で使用されるポインタ安全性。

例

このコードを実行 
#include <iostream>
#include <memory>
int main()
{
    std::cout << "Pointer safety: ";
    switch (std::get_pointer_safety())
    {
        case std::pointer_safety::strict:
            std::cout << "strict\n";
            break;
        case std::pointer_safety::preferred:
            std::cout << "preferred\n";
            break;
        case std::pointer_safety::relaxed:
            std::cout << "relaxed\n";
            break;
    }
}

出力例: 

Pointer safety: relaxed
