Diese Memberfunktion geschützt ist: Es wird von den Konstruktoren der abgeleiteten Stream-Klassen genannt std::basic_istream und std::basic_ostream einmal die zugehörige Strompuffers bekannt ist. Bis diese Funktion aufgerufen wird, ruft jedes Mitglied Funktion (andere als die destructor) der default-konstruiert std::basic_ios undefiniertem Verhalten. Beachten Sie, dass basic_ios eine virtuelle Basisklasse ist, und daher seinen Konstruktor wird von den Konstruktoren der direkt abgeleiteten Klassen, weshalb zweistufigen Initialisierung ist notwendig bezeichnet .

Original:

This member function is protected: it is called by the constructors of the derived stream classes std::basic_istream and std::basic_ostream once the associated stream buffer is known. Until this function is called, every member function (other than the destructor) of the default-constructed std::basic_ios invokes undefined behavior. Note that basic_ios is a virtual base class, and therefore its constructor is not called by the constructors of those directly derived classes, which is why two-stage initialization is necessary.
