パラメーター

名前	型	方向	説明
hGroup	HGROUP	in	制御操作の対象クラスターグループのハンドル。
hHostNode	HNODE	inoptional	操作を実行するホストノードのハンドル。NULLで所有ノードを使用。
dwControlCode	DWORD	in	実行する制御コード。CLUSCTL_GROUP_*値で指定する。
lpInBuffer	void*	inoptional	制御コードへの入力データを格納したバッファ。不要時はNULL。
nInBufferSize	DWORD	in	lpInBufferのバイト数。
lpOutBuffer	void*	outoptional	出力データを受け取るバッファ。NULLでサイズ取得可。
nOutBufferSize	DWORD	in	lpOutBufferのバイト数。
lpBytesReturned	DWORD*	outoptional	実際に出力されたバイト数を受け取るDWORDへのポインタ。
