Defined in header

enum class pointer_safety {
(since C++11) relaxed,
preferred,
strict
(removed in C++23)
The scoped enumeration type pointer_safety lists the pointer safety modes supported by C++.
[edit] 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.
