SEH例外.默认情况下，使用EXCEPTION_CONTINUE_EXECUTION处理哪些SEH异常? [英] SEH Exceptions. What SEH exceptions are processed by default with EXCEPTION_CONTINUE_EXECUTION?

问题描述

在哪里可以找到有关默认情况下如何处理SEH异常的信息? MSDN中没有此类信息.但是我需要这些信息来了解必须忽略哪些异常，然后使用EXCEPTION_CONTINUE_SEARCH将它们传递给系统.我的意思是处理了哪些SEH例外 默认情况下使用EXCEPTION_CONTINUE_EXECUTION，这就是为什么我的应用程序不终止并继续执行的原因?这就是为什么我不能在__except过滤器中使用EXCEPTION_EXECUTE_HANDLER处理它们的原因.

Where can I find information how SEH exceptions are processing by default? There is no such info in MSDN. But I need this information to know what exceptions I must ignore and pass them to system with EXCEPTION_CONTINUE_SEARCH. I mean what SEH exceptions are processed by default with EXCEPTION_CONTINUE_EXECUTION and that's why my application don't terminated and continue execution? That's why I must not processing them with EXCEPTION_EXECUTE_HANDLER in the __except filter.

这些都来自WinBase.h:

推荐答案

简单的规则是只处理您需要的内容.通过处理所有异常，您可能会无意间妨碍很多事情.

The simple rule is handle only what you need to. You can inadvertantly get in the way of a lot of things by handling all exceptions.

您最好的选择是默认情况下忽略异常，但仅处理特定列表，这是所有示例向您展示如何做到的方式.那是

Your better bet is to ignore exceptions by default but only handle a certain list, and it is the way all samples show you how to do it. That is

__except(GetExceptionCode() == EXCEPTION_ACCESS_VIOLATION ? EXCEPTION_EXECUTE_HANDLER : EXCEPTION_CONTINUE_SEARCH )
