定義於標頭檔案 <memory>
std::pointer_safety get_pointer_safety() noexcept;		(C++11 起) (在 C++23 中移除)

獲取實現定義的指標安全模型，它是一個 std::pointer_safety 型別的值。

引數

(無)

返回值

此實現使用的指標安全型別。

示例

執行此程式碼

#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;
    }
}

可能的輸出

Pointer safety: relaxed
