WorkerThreadCreation Event

Fires just after a new worker thread is created.

Syntax

class CBProcessWorkerThreadCreationEventParams {
public:
  int ResultCode();
  void SetResultCode(int iResultCode);
  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void WorkerThreadCreation(CBProcessWorkerThreadCreationEventParams *e);
// Or, subclass CBProcess and override this emitter function. virtual int FireWorkerThreadCreation(CBProcessWorkerThreadCreationEventParams *e) {...}

Remarks

This event fires just after a worker thread is created, in the context of that worker thread.

This event is optional; it is provided to give applications a chance to perform additional processing when a new worker thread is created, such as allocating 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.

The ResultCode parameter will always be 0 when the event is fired. If the event cannot be handled in a "successful" manner for some reason (e.g., a resource isn't available, security checks failed, etc.), set it to a non-zero value to report an appropriate error. Please refer to the Error Reporting and Handling topic for more information.

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