# std::basic_ios::swap

From cppreference.com
< cpp‎ | io‎ | basic ios

protected: void swap( basic_ios& other ); |  | (since C++11)

Exchanges the states of *this and `other`, except for the associated `rdbuf` objects. rdbuf() and other.rdbuf() returns the same values as before the call.

This swap function is protected: it is called by the swap member functions of the derived stream classes such as std::basic_ofstream or std::basic_istringstream, which know how to correctly swap the associated streambuffers.
