I am using a CSemaphore object with a count of 1. I use the CSingleLock object to provide the access control. I have two tasks which I am synchronising. I lock the semaphore with the first task using CSingleLock::Lock and then do the same in the second task with an INFINITE wait so that when the first task then uses Unlock to unlock the semaphore the second task can procede in sync with the first task. My problem is that in a DEBUG release I get an ASSERT because I am trying to lock a semaphore that is already locked. But this does not make sense to me because that is what semaphores are for are they not ? Or am I being stupid ?
Help would be greatly appreciated.
p.s. I have tried FAQ on Dejanews but there seems to be no official answer.
