NAME¶

std::pointer_safety - std::pointer_safety

Synopsis¶

Defined in header <memory>
enum class pointer_safety {

relaxed, (since C++11)
preferred, (removed in C++23)
strict

};

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

Enumeration constants

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