|
The scoped enumeration type pointer_safety lists the pointer safety modes supported by C++.
[edit] 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. |
[edit] See also
| (C++11)(removed in C++23) |
returns the current pointer safety model (function) |
