std::basic_ios::swap

性病：基本[医]IOS：：全部门办法

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

交换状态*this和other，除了相关的rdbuf物品。rdbuf()和other.rdbuf()返回与调用前相同的值。

此交换函数受到保护：它由派生流类的交换成员函数调用，如std::basic_ofstream或std::basic_istringstream，它们知道如何正确地交换相关的流缓冲区。

参数

other-the basic_ios object to exchange the state with

返回值

%280%29

例外

noexcept规格：

noexcept

另见

move (C++11)moves from another std::basic_ios except for rdbuf (protected member function)
