Объект класса basic_ostream::sentry построен в локальной области в начале каждого члена функции std::basic_ostream, который выполняет вывод (как форматированных и неформатированных). Его конструктор готовит выходной поток: чеки, если поток уже находится в состоянии сбоя, приливы галстук () 'г потоки продукции, а также выполняет другие реализации определенных задач, если это необходимо. Реализация определенных очистки, а также промывка выходного потока, если это необходимо, выполняется в деструкторе, так что он гарантированно случится, если исключений во время вывода.

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.
