    Le constructeur par défaut est protégé: seuls les classes dérivées peuvent std::ios_base construire. L'état interne est indéfini après la construction. La classe dérivée doit appeler basic_ios::init() pour terminer l'initialisation avant la première utilisation ou avant destructeur, sinon le comportement est indéfini .
    Original:
    The default constructor is protected: only derived classes may construct std::ios_base. The internal state is undefined after the construction. The derived class must call basic_ios::init() to complete initialization before first use or before destructor, otherwise the behavior is undefined.

    Notes

    La même chose vaut pour les constructeurs de la classe supérieure dans la hiérarchie d'E / S, std::basic_ios. De plus les classes dérivées (std::istream et std::ostream) sont toujours construits avec un objet streambuffer béton et basic_ios::init() appel, peut-être plus d'une fois, pour terminer l'initialisation de leur base virtuelle .
    Original:
    The same applies to the constructors of the next class in the I/O hierarchy, std::basic_ios. Further-derived classes (std::istream and std::ostream) are always constructed with a concrete streambuffer object and call basic_ios::init(), possibly more than once, to complete initialization of their virtual base.
