Use of Win32 semaphore

[bug_crusher]

Hello,

Is it possible to use a semaphore to prevent a single thread from recursing infinitely ? I am handling a notification message, and unfortunately my handler causes the notification to be Sent again on some machines. I need to find a way to know that I am already handling that message so that I can ignore it when it comes in again. Can this be done?

Thanks

The answer should be yes.
