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
Parameters
p | - | a safely-derived pointer or a null pointer |
Return value
(none)
Exceptions
May throw std::bad_alloc if the system cannot allocate memory required to track reachable objects.
