    void declare_reachable( void* p )
    		 (seit C++11)
    Deklariert die Aufgabe durch die Zeiger referenzierten p erreichbar sind. Erreichbaren Objekte werden nicht vom Garbage Collector gelscht werden oder als ein Leck mit einem Leckdetektor selbst wenn alle Zeiger auf sie zerstrt werden. Ein Objekt kann erreichbar mehrfach, in welchem Fall mehrere Aufrufe std::undeclare_reachable bentigt, um diese Eigenschaft zu entfernen wrden deklariert werden. Zum Beispiel muss ein XOR verketteten Liste seine Knotenpunkte erreichbar zu erklren, wenn die Umsetzung ist Garbage Collection aktiviert .
    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 verketteten Liste needs to declare its nodes reachable if the implementation has garbage collection enabled.
