Defined in header <memory>
template< class T > T* undeclare_reachable( T* p )		(ya que C + +11)

Elimina el estado del objeto accesible, al que hace referencia el puntero p, si se ha establecido previamente por std::declare_reachable. Si el objeto se declaró alcanzables varias veces, igual número de llamadas a undeclare_reachable sería necesaria para eliminar esta condición. Una vez que el objeto no se ha declarado accesible y no tiene punteros haciendo referencia a ella, puede ser reclamado por el recolector de basura o reportado como una fuga por un detector de fugas .

Original:

Removes the reachable status of the object, referenced by the pointer p, if it was previously set by std::declare_reachable. If the object was declared reachable multiple times, equal number of calls to undeclare_reachable would be needed to remove this status. Once the object is not declared reachable and has no pointers referencing it, it may be reclaimed by garbage collector or reported as a leak by a leak detector.
