What is the lifetime of your created thread?  Does it live for the life of the IOC, or does it immediately exit when it has done its calculation?

 

In any case, you should be able to just create the event once at initialization.  When the thread is created it needs a way to be passed the epicsEventId of the event you previously created.

Hi
i want to learn how we can use epicsEvents in asynDriver.
In multi-threading in epics. I want to pass signal form scanning thread to other created thread.
I am not clear where i have to create epics event and where to destroy.

In my asynDriver i am creating epicsThread at initialisation then wait for signal (epicsEventWait) form scanning thread to calculate some value. I am signal to this thread with epicsEventSignal form asynInt32Write function.

In this case i have to create event (epicsEventCreate) at initialisation before creating thread or at scanning thread and destroy event after completion of created thread ( in this case every time event is created and destroy-> is it good for asynDriver development?) . or create event at created thread and destroy after completion of calculation.




Thank you
