参数

(无)

返回值

此实现所使用的指针安全性。

示例

运行此代码 
#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;
    }
}

可能的输出： 

Pointer safety: relaxed
