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

获得实现定义的指针安全模式，它是 std::pointer_safety 类型的值。

参数

（无）

返回值

此实现所用的 pointer_safety 。

示例

#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
