void swap( basic_iostream& other ); |

Exchanges the state with another input/output stream object. Effectively calls basic_istream<CharT,Traits>::swap(other).
This member function is protected: it is called by the swap member functions of the derived stream classes std::basic_stringstream and std::basic_fstream, which know how to correctly swap the associated stream buffers.
