Defined in header <memory>
enum class pointer_safety {      relaxed,      preferred,      strict };		(since C++11) (removed in C++23)

The scoped enumeration type pointer_safety lists the pointer safety modes supported by C++.

Enumeration constants

Enumerator	Meaning
pointer_safety::strict	Only safely-derived pointers (pointers to objects allocated with new or subobjects thereof) may be dereferenced or deallocated. Garbage collector may be active.
pointer_safety::preferred	All pointers are considered valid and may be dereferenced or deallocated. A reachability-based leak detector may be active.
pointer_safety::relaxed	All pointers are considered valid and may be dereferenced or deallocated.
