什么时候可以从C ++中的析构函数抛出异常？ [英] When is it OK to throw an exception from a destructor in C++?

问题描述

我知道规则是在析构函数中不要抛出一个规则，我明白为什么。我不敢做但是即使是C ++ Faq Lite，这个规则也是99％的时间。他们未能深入研究的其他1％是什么？

解决方案

只是不要这样做。
如果星星和行星按照您需要的方式对齐...

仍然不要这样做。

I know the rule is to NEVER throw one during a destructor, and I understand why. I would not dare do it. But even the C++ Faq Lite says that this rule is good 99% of the time. What is the other 1% that they fail to delve into?

解决方案

Just don't do it. If the stars and planets align in such a way that you find you need to...

Still don't do it.
