save windows handle - an interesting question

[leejwen]

I create a windows handle (doesnt matter what handle). I'd like to share it with other applications. So I create a share-memory to keep it. Can it be used by other apps? Why?. Is there any other alternatives to share you handles to other applications?

There's a good presentation of this in Windows via C/C++ by Jeffrey Richter 2008 pages 43-64 about sharing kernal objects.

I would get a copy of this book.
