Re: RE: Timing events in GNAT GPL 2006


There are three things wrong with your codes. Two of them are critical.
1. The protected procedure Inc_Clock has wrong parameter mode. It must
be in out mode.
2. The call Set_Handler from the protected procedure will result in a
deadlock it is run.
3. Protected object must be declared at the library level. Yours is not.
As the result, non-local pointer cannot point to local object error at
lines 20 and 26

OK, I fixed issues 1 and 3 in my code and I can observe issue 2. I don't understand, however, why the deadlock occurs. Is the deadlock required by the RM or is it just due to GNAT's implementation of Timing_Events?

I designed for both one shot and periodic timers using Timing Event. If
it is helpful, I will post my code here. Just let me know.

Although I found by now your discussion from around March 2006, I'd like to see your code.

Thanks for your fast response.
