c++ - C++11 File Streams

Question

Has C++11 move semantics made the use of std::ifstream and std::ofstream easier or safer with regards to exceptions? I guess it depends on the standard library aswell. Any differences there between GCC, ICC and VC++ Compiler?

Answer 1

不会。std::stream 类的异常安全方面没有受到影响。唯一的区别是您现在可以从工厂函数返回流并将它们存储在容器中。
