Wineg++ and structured exception handling

[Michael Ost]

Hi,

Is there a way for wineg++ to catch windows exceptions and handle them 
as g++ does --- cleaning up stack variables, etc?

My C++ winelib app, built with wineg++, is loading Windows DLLs. I want 
to catch windows exceptions from functions that I call from those DLLs. 
I need to do some cleanup if there are exceptions, and tried creating 
some stack variables to manage that.

I found __TRY and __CATCH in wine/exception.h. Wrapping the DLL function 
calls with __TRY and __CATCH does indeed catch exceptions, but there is 
no stack cleanup.

There is some deep code in exception.h that implements __TRY/__CATCH 
(which I sure could be misreading) but they look more C like than C++ 
like... just taking care to jump to the right location without trying to 
do any cleanup.

Window's c++ compiler evidently does that now, per this page: 
http://msdn.microsoft.com/en-us/library/7w0chfbk(VS.80).aspx

I'm guessing I am out of luck here, but am hoping I'm just missing 
something.

Thanks... mo

Wow, I remember discovering this area of winelib about 4 years ago and
wondering if anyone else was working on it or using it.  Great to hear
about you :)
