Defined in header <memory>
void declare_reachable( void* p )
(desde C++11)
Declara el objeto referenciado por el apuntador p accesible. Objetos accesibles no serán eliminados por el recolector de basura o que se considera una fuga por un detector de fugas incluso si todos los indicadores de que se destruyan. Un objeto puede ser declarado accesibles en múltiples ocasiones, en cuyo caso varias llamadas a std::undeclare_reachable serían necesarias para eliminar esta característica. Por ejemplo, un XOR lista enlazada necesita declarar a sus nodos alcanzable si la aplicación tiene la recolección de basura habilitada .
Original:
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 lista enlazada needs to declare its nodes reachable if the implementation has garbage collection enabled.
