std::declare_reachable
From cppreference.com
| Defined in header <memory>

||
| void declare_reachable( void* p ); |
(since C++11) (removed in C++23) |
|
Declares the object referenced by the pointer p reachable. Reachable objects will not be deleted by the garbage collector or considered to be a leak by a leak detector even if all pointers to it are destroyed. An object may be declared reachable multiple times, in which case multiple calls to std::undeclare_reachable would be needed to remove this property. For example, a XOR linked list needs to declare its nodes reachable if the implementation has garbage collection enabled.
