クラスbasic_ostream::sentryのオブジェクトが出力（フォーマット済みと未フォーマットの両方）を実行std::basic_ostreamの各メンバ関数の先頭でローカルスコープで構成されている。ストリームがすでに失敗した状態にあるかどうかをチェックし、フラッシュするのtie（） 'd出力ストリーム、および必要に応じて他の実装で定義されたタスクを実行します。そのコンストラクタは出力ストリームを準備します。実装定義クリーンアップだけでなく、出力ストリーム、必要に応じてのフラッシュは、それは例外が出力中にスローされる場合に発生することが保証されているように、デストラクタで行われ.

Original:

An object of class basic_ostream::sentry is constructed in local scope at the beginning of each member function of std::basic_ostream that performs output (both formatted and unformatted). Its constructor prepares the output stream: checks if the stream is already in a failed state, flushes the tie()'d output streams, and performs other implementation-defined tasks if necessary. Implementation-defined cleanup, as well as flushing of the output stream if necessary, is performed in the destructor, so that it is guaranteed to happen if exceptions are thrown during output.
