Waiting for threads

[Raffael Herzog]

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
