WorkerThreadTermination Event

Fires just before a worker thread is terminated.

Syntax

class CBFilterWorkerThreadTerminationEventParams {
public:
  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.

// Or, subclass CBFilter and override this emitter function.
virtual int FireWorkerThreadTermination(CBFilterWorkerThreadTerminationEventParams *e) {...}

Remarks

This event fires just before a worker thread is terminated, in the context of that worker thread.

This event is optional; it is provided to give applications a chance to perform additional processing before a worker thread is terminated, such as deallocating per-thread objects.

The class maintains a pool of worker threads and uses them to fire events; please refer to the Threading and Concurrency topic for more information.

Any errors that occur during this event are ignored.

This event is fired synchronously; please refer to the Event Types topic for more information.
