中止，终止或退出？ [英] abort, terminate or exit?

问题描述

推荐答案

我的建议是不要使用任何一个。相反，捕获你不能在main（）中处理的异常，只是从那里返回。这意味着您可以确保堆展开正确发生，并调用所有析构函数。换句话说：

My advice would be not to use any of them. Instead, catch the exceptions you can't handle in main() and simply return from there. This means that you are guaranteed that stack unwinding happens correctly and all destructors are called. In other words:

int main() {
    try {
       // your stuff
    }
    catch( ... ) {
       return -1;    // or whatever
    }
}
