std::ostreambuf_iterator является один проход выходного итератора, который пишет последовательных символов в std::basic_streambuf объекта, для которого она была построена. Фактически операция записи выполняется, когда итератор (будь разыменован или нет) назначен. Приращение std::ostreambuf_iterator является не-оп.

Original:

std::ostreambuf_iterator is a single-pass output iterator that writes successive characters into the std::basic_streambuf object for which it was constructed. The actual write operation is performed when the iterator (whether dereferenced or not) is assigned to. Incrementing the std::ostreambuf_iterator is a no-op.

В типичной реализации, только члены данных std::ostreambuf_iterator являются указатель на связанный std::basic_streambuf и логический флаг, указывающий, если конец файла условиях была достигнута.

Original:

In a typical implementation, the only data members of std::ostreambuf_iterator are a pointer to the associated std::basic_streambuf and a boolean flag indicating if the the end of file condition has been reached.
