} ;
(since C++11)
(removed in C++23)

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

Enumeration constants

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.
