rhs. Эта функция подкачки защищен: его называют своп функции замены классы выходного потока std::basic_ofstream и std::basic_ostringstream, которые знают, как правильно поменять связанных streambuffers.Original:
Calls basic_ios::swap(rhs) to swap all data members of the base class, except for rdbuf(), between *this and
rhs. This swap function is protected: it is called by the swap functions of the swappable output stream classes std::basic_ofstream and std::basic_ostringstream, which know how to correctly swap the associated streambuffers.The text has been machine-translated via Google Translate.
