Defined in header <memory>
template< class T >
T* undeclare_reachable( T* p )
(C + + 11以来)
それが以前pによって設定された場合は、ポインタstd::declare_reachableによって参照されるオブジェクトの到達可能な状態を削除します。オブジェクトが到達可能な複数回宣言された場合、undeclare_reachableへのコールの数と同じ数は、このステータスを削除するのに必要でしょう。オブジェクトは到達可能と宣言し、それを参照していないポインタをもつされていないと、それはガベージコレクタによって回収やリークディテクタでリークとして報告されることがあります.
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.
