std::get_pointer_safety

Defined in header <memory>
std::pointer_safety get_pointer_safety() noexcept;
(since C++11)
(removed in C++23)

Obtains the implementation-defined pointer safety model, which is a value of type std::pointer_safety.

Parameters

(none).

Return value

The pointer safety used by this implementation.

Example

#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;
    }
}

Possible output:

Pointer safety: relaxed
