定义于头文件 <memory>
std::pointer_safety get_pointer_safety() noexcept;		(始于 C++11) (C++23 中移除)

获取实现定义的指针安全性模型，其为 std::pointer_safety 类型的值。

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
