basic_ios::swap
(C++11)
(C++11)
protected:
void swap( basic_ios& other ) noexcept;
(since C++11)
void swap( basic_ios& other ) noexcept;
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 stream buffers.
[edit] Parameters
other
-
the
basic_ios object to exchange the state with
