パラメーター

名前型方向説明
ObjectHandleHANDLEin依存情報を取得する対象のVHDまたはボリュームのハンドル。OpenVirtualDiskやファイルハンドルで指定する。
FlagsGET_STORAGE_DEPENDENCY_FLAGin取得動作を制御するGET_STORAGE_DEPENDENCY_FLAGのビットフラグ。親チェーン取得など対象範囲を指定する。
StorageDependencyInfoSizeDWORDin出力バッファStorageDependencyInfoのサイズをバイト単位で指定する。0でサイズ問い合わせが可能。
StorageDependencyInfoSTORAGE_DEPENDENCY_INFO*inout依存情報を受け取るSTORAGE_DEPENDENCY_INFO構造体へのポインタ。Versionを事前設定する出力バッファ。
SizeUsedDWORD*inoutoptional実際に使用または必要となったバイト数を返すDWORDポインタ。バッファ不足時の必要量取得に使う。
