std::ios_base::ios_base

科技促进发展：监督办[医]基础：：监督办[医]底座

​(1)​
private: ios_base( const ios_base& (until C++11)
public: ios_base( const ios_base& ) = delete;(since C++11)
protected: ios_base((2)​

1%29复制构造器被删除：流不可复制。

2%29默认构造函数受到保护：只有派生类才能构造std::ios_base内部状态在施工后不确定。派生类必须调用basic_ios::init()若要在第一次使用之前或在析构函数之前完成初始化，则行为未定义。

注记

这同样适用于I/O层次结构中下一个类的构造函数，std::basic_ios进一步衍生类别%28std::istream和std::ostream%29总是使用具体的流缓冲区对象构造，并调用basic_ios::init()，可能不止一次，以完成其虚拟基础的初始化。
