有什么办法得到一些信息，至少为catch（...）？ [英] Is there any way to get some information at least for catch(...)?

问题描述

有没有办法在这里获得至少一些信息？

Is there any way to get at least some information inside of here?

...
catch(...)
{
  std::cerr << "Unhandled exception" << std::endl;
}

我将这作为我所有代码的最后手段。

I have this as a last resort around all my code. Would it be better to let it crash, because then I at least could get a crash report?

推荐答案

不，没有，没有，任何方式。尝试使所有的异常类从一个单独的类派生，如 std :: exception ，然后捕获那个。

No, there isn't any way. Try making all your exception classes derive from one single class, like std::exception, and then catch that one.

您可以在嵌套的尝试中重新抛出，试图找出类型。但是你也可以使用以前的catch子句（和 ... 只能作为后退）。

You could rethrow in a nested try, though, in an attempt to figure out the type. But then you could aswell use a previous catch clause (and ... only as fall-back).
