How can I register an exit routine for my dll and ensure it would be run for all ABNORMAL process terminations?  I cannot use try, catch method because this only handles synchronous cases.  I need some way to be notify of termination regardless which part of the code is excuting at the time of the exit, something like a signal handler?

I believe there is no generic solution to this problem. What you could try is writing some 'dr watson' like utility that knows about your program and kills the DLL's you are using when your program does an abnormal termination.

There is no way to catch you program internally when it goes off the deep end through some kind of GPF or something like that.

What about using set_terminate(terminate_function term_func)?  Would the term_func gets called for all abnormal termination??

I could not find that function. Which API is it in?
I imagine that it is similar to the at_exit function and the registered functions with that are only called when the programs terminate via exit or falling of the end of main.

The function prototype can be found in the "eh.h" file.  This function is also mentioned in the on-line documentation.  However, I am still not very sure exactly when it will be called.
