std::declare_reachable
From cppreference.com
| Defined in header <memory>
|
||
| void declare_reachable( void* p ); |
(since C++11) | |
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.
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.
