std::pointer_safety

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

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

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

(C++11)

returns the current pointer safety model
