Non-member functions

swap(std::basic_ofstream) (C++11)

 

basic_ofstream& operator=( basic_ofstream&& other );		(since C++11)

Move assigns the file stream other to *this, effectively move-assigning both the std::basic_ostream base class and the associated std::basic_filebuf.

other is left with no associated file. Note that the base class move assignment swaps all stream state variables (except for rdbuf) between *this and other.

Parameters

other

-

file stream to move.

Return value

*this

swap (C++11)	swaps two file streams (public member function)
operator= (C++11)	assigns a basic_filebuf object (public member function of std::basic_filebuf<CharT,Traits>)
operator= (C++11)	move-assigns from another basic_ostream (protected member function)
