パラメーター

名前方向説明
TransactionHandleHANDLEinトランザクションへのハンドル。情報を取得するには、このハンドルに TRANSACTION_QUERY_INFORMATION 権限が必要です。
OutcomeDWORD*inoutトランザクションの現在の結果を受け取るバッファーへのポインター。GetTransactionInformation 関数の呼び出しが成功した場合、この値は TRANSACTION_OUTCOME 列挙体の値のいずれかになります。
IsolationLevelDWORD*inout予約されています。
IsolationFlagsDWORD*inout予約されています。
TimeoutDWORD*inoutこのトランザクションのタイムアウト値(ミリ秒単位)を受け取る変数へのポインター。
BufferLengthDWORDinDescription パラメーターのサイズ(バイト単位)。バッファー長の値は MAX_TRANSACTION_DESCRIPTION_LENGTH の値を超えることはできません。
DescriptionLPWSTRoutoptionalトランザクションのユーザー定義の説明を受け取るバッファーへのポインター。

戻り値の型: BOOL

公式ドキュメント

指定したトランザクションについて、要求された情報を返します。

戻り値

関数が成功した場合、戻り値は 0 以外になります。

関数が失敗した場合、戻り値は 0 になります。拡張エラー情報を取得するには、GetLastError 関数を呼び出します。

次の一覧に、発生し得るエラーコードを示します。
