sem_timedwait always decrements semaphore value

Open fdgonthier opened this issue 2 years ago • 1 comments

On entering the sem_timedwait function the semaphore value is (correctly?) decremented but it is never reset to its original value when xSemaphoreTake returns a timeout. In my case, this means that in a loop where sem_timedwait is called with a timeout, the value of the semaphore keeps getting more negative.

A patch is forthcoming as I need this to work.

@fdgonthier : Did you ever get this working as expected? We would greatly appreciate a patch if so.
