Structured exception

Hello everyone,


I am learning structured exception from,

http://msdn2.microsoft.com/en-us/lib...09(VS.85).aspx

I read a couple of links from MSDN, but still confused what is structured exception, what is the differences between structure exception and our normal C++ exception, like bad_alloc and various user define exception?


thanks in advance,
George

Moved to Win32.

Structured exceptions are a Win32-specific thing.

C++ exceptions are a C++-specific thing.

C++ exceptions carry an object. Structured exceptions carry just a code. SEH has finally blocks. SEH allows continuation.

Most Win32 compilers implement C++ exceptions using SEH.

That's it, pretty much. The purpose is the same.

Thanks CornedBee,


I also read some structured exception tutorials, especially this one I think is perfect,

http://www.microsoft.com/msj/0197/Ex...Exception.aspx

1.

I think structured exception is totally different from C++ exception, even if the purpose and the logics are the same, right?

Previously, I mis-understand that structured exception is a special kind of C++ exception, which is wrong.

2.

Why in normal code and API document (like MSDN ones), I have almost never seen structured exception and only see almost all are C++ exception?


regards,
George

They are two completely distinct things, if that's what you mean.

I've never seen a C++ exception in the WinAPI documentation. Only in the documentation of the C++ standard library. Which makes sense.

So you mean you see some structured exception in WinAPI? Could you send me a sample MSDN link please? :-)
