Is there any way to use C++ exceptions in kernel mode?

Anyway? Sure just port the c++ exception handling runtime support into the
kernel. The code, or a reasonable facsimile thereof is probably found in the
rtl library source code shipped with the VisualStudio 6 complete
distribution. You might want to search this list and the newsgroups (google)
for the various discussions of this topic as it has been covered in
nauseating detail repeatedly. It ought to be in a FAQ somewhere.

Here was one thread in google that popped up:

Oh yes. Check Walter Oney’s book, and I believe there are a toolkits that
utilize C++.

What’s wrong with the built-in and supported Structured Exception Handling?

There are a couple of things that SEH doesn’t handle and I wish it would.
For example, I’d like to use “self unlocking” mutexes, when I aquire it in
the constructor and release in destructor. This way I don’t have to remember
to release it before every “return” instruction. This technics (and not only
for mutexes) makes my life much easier. Unfortunatelly, with SEH (unlike
regular C++ exc.) it’s not always guaranteed that my destructor will be
called.

Vladimir

Isn’t __finally available to use? If it were, it could be used to tidy up
in exceptional exit situations.

logic kicks ass:
(1) Horses have an even number of legs.
(2) They have two legs in back and fore legs in front.
(3) This makes a total of six legs, which certainly is an odd number of
legs for a horse.
(4) But the only number that is both odd and even is infinity.
(5) Therefore, horses must have an infinite number of legs.

Sure, __finally is available! But still you have to do the cleanup
explicitly, “by hands”.

Hmm, Outlook reports, that this message is formatted as a “Plain text”. Why
the heck it appears as HTML?
