Callasync locking?


Hi guys,

Is is correct that MessageManager::callasync does some locking?
The MessageQueue class that is used two keep a list of all messages has a ReferenceCountedArray messages which takes a criticalsection(mutex) to prevent some conclicts with reading and writing to this array.

Could this be a problem or am I just afraid for nothing…?

Thanks in advance,


What does the implementation of callAsync() do? Do you see any locking happening in the implementation?


Well… callAsync creates an AsyncCallInvoker on the heap (which is also not so nice if you call that on the audio thread). And that class calls the post() method from MessageBase which calls postMessageToSystemQueue(), which calls post() on a MessageQueue, which then adds the messagebase to an array which takes a criticalsection.
So that array uses locking. But maybe this is just a small, fast, lock.
