パラメーター

名前	型	方向	説明
Flags	DWORD	in	列挙制御フラグ。DIBCI_NOINSTALLCLASS等で対象クラスを絞り込む。0で既定動作。
ClassGuidList	GUID*	outoptional	インストール済みクラスGUID配列を受け取るバッファ。
ClassGuidListSize	DWORD	in	ClassGuidList配列が保持できるGUID要素数。
RequiredSize	DWORD*	out	実際に必要なGUID要素数を受け取るポインタ。サイズ照会に使う。
MachineName	LPCWSTR	inoptional	対象リモートコンピュータ名(Unicode)。NULL指定でローカルマシンを対象とする。
Reserved	void*	optional	予約済み。NULLを指定する。
