1) there was a smiley in my message!
2) I think we have come to the conclusion that a void* is indeed a more
powerfull API with little performance impact (as you can cast the void*
to an int to get your vector number). Concerning portability, as I
already mentionned often in this newgroup, *IRQ HANDLING SHOULD REMAIN
BSP SPECIFIC* meaning that you are not forced to change the API at all
on non standart platform. If you just want to benefit the enhancement
made by others, then this will cost you more and more time due to
API/build enevironment cahnges that will occur.

OK but if an API prevent to port rtems easilly to a hardware that is not
too much exotic, maybe it means that the API is flowed...

Do you know Canon IP policy? Do you know the patenting pressure I had to
fight all those past 7 years. So believe me, you can change things if
you explain that submitting code cost less money and do not divulgate
company know how...
