C ++-捕获所有异常？

Question

I want to inject a DLL into a process. Once this DLL is in there, it should catch & properly handle all access violation exceptions which occur in the process. Is there any way to accomplish this?

Answer 1

How about SetUnhandledExceptionFilter( function )?

function 's prototype is:

LONG __stdcall ExceptionHandler(EXCEPTION_POINTERS *ExceptionInfo);

I've used this function to create crash dumps, etc.

Answer 2

You can use Structured Exception Handling (SEH) to catch such exceptions. Specifically, this Windows function seems to be what you want to do.

Answer 3

要完成收集，您还可以使用AddVectoredExceptionHandler 。

Answer 4

Pre XP, you cannot catch all exceptions. XP or later, you should use AddVectoredExceptionHandler(1, handler) , although you are not guaranteed that you will always be the first vectored exception handler.
