Waiting for threads

Hi,

Situation:

- An object (a) starts a new thread when initialized
- This object a is also a factory for other objects (b), each of which starts its own thread, too - When object a receives a dealloc message, it sets its status accordingly causing all those threads to exit ASAP

The problem is this "ASAP". I don't know exactly *when* a thread actually exited, but I need to make sure that all dependent threads have exited before the object that started them gets deallocated. What I'm looking for is something like Thread#join() in Java:

Thread myThread = new Thread(myRunnable);
myThread.start();
// do something...
myThread.requestStop(); // ask the detached thread to exit
myThread.join(); // wait until the thread actually exited

How can this be achieved with GNUstep?


TIA,
  Raffi
