Re: [Corelinux-develop] ChangeLog and Feature/Defect fixes

[Frank V. C. <fr...@co...>]

Ok, couple of things:

1. I change the listener counters in EventSemaphore to type Counter
(which is signed) from Count (which is unsigned).
2. I wrapped the include <sys/sem.h> in extern "C"

So the code looks good there, but, question, and if you already answered
this I'm sorry:

Given the scenario where I have two listeners and (obviously) one
controller

1. The controller creates the semaphore and it is locked
2. The listeners come in and block on the wait (wait(0))
3. The controller releases the semaphore
4. The listeners, in a tight loop, come right back in and try to block
again

Because the controller has released but not regained the control (-1),
this will mean that the listeners will behave as though they got another
event, while in actuality they haven't, correct?
