basic_iostream Class

A stream class that can do both input and output.

template <class Elem, class Tr = char_traits<Elem> >
    class basic_iostream : public basic_istream<Elem, Tr>,
        public basic_ostream<Elem, Tr>
    explicit basic_iostream(basic_streambuf<Elem, Tr> *_Strbuf);
    virtual ~basic_iostream();

The template class describes an object that controls insertions, through its base class basic_ostream<Elem, Tr>, and extractions, through its base class basic_istream<Elem, Tr>. The two objects share a common virtual base class basic_ios<Elem, Tr>. They also manage a common stream buffer, with elements of type Elem, whose character traits are determined by the class Tr. The constructor initializes its base classes through basic_istream(strbuf) and basic_ostream(strbuf).


Create a basic_iostream object.


Exchanges the contents of the provided basic_iostream object for the contents of this object.


Assigns the value of a specified basic_iostream object to this object. This is a move assignment involving an rvalue that does not leave a copy behind.
