The class basic_iostream inherits a number of functions that allow reading input and writing output to sequences controlled by a stream buffer.
explicit basic_iostream(basic_streambuf<charT,traits>* sb);
basic_iostream(basic_iostream&& rhs);
Effects: Move constructs from the rvalue rhs by constructing the basic_istream base class with move(rhs).
Effects: Destroys an object of class basic_iostream.
Remarks: Does not perform any operations on rdbuf().
basic_iostream& operator=(basic_iostream&& rhs);
Effects: swap(rhs).
void swap(basic_iostream& rhs);
Effects: Calls basic_istream<charT, traits>::swap(rhs).
