std::basic_fstream::swap

性病：基本[医]fstream：：swp

void swap( basic_fstream& other ​(since C++11)

将流的状态与other...

实现的办法是调用basic_iostream<CharT, Traits>::swap(other)和rdbuf()->swap(other.rdbuf())...

参数

other-stream to exchange the state with

返回值

%280%29

例

另见

operator= (C++11)moves the file stream (public member function)
swap (C++11)swaps two basic_filebuf objects (public member function of std::basic_filebuf)
