namespace std { template<class charT, class traits = char_traits<charT>> class basic_iostream : public basic_istream<charT, traits>, public basic_ostream<charT, traits> { public: using char_type = charT; using int_type = typename traits::int_type; using pos_type = typename traits::pos_type; using off_type = typename traits::off_type; using traits_type = traits; // [iostream.cons], constructor explicit basic_iostream(basic_streambuf<charT, traits>* sb); // [iostream.dest], destructor virtual ~basic_iostream(); protected: // [iostream.cons], constructor basic_iostream(const basic_iostream&) = delete; basic_iostream(basic_iostream&& rhs); // [iostream.assign], assignment and swap basic_iostream& operator=(const basic_iostream&) = delete; basic_iostream& operator=(basic_iostream&& rhs); void swap(basic_iostream& rhs); }; }
The class template basic_­iostream inherits a number of functions that allow reading input and writing output to sequences controlled by a stream buffer.
