ISpThreadTask::ThreadProc

This method implements the main processing loop of a thread. This method is application-specific.

virtual HRESULT STDMETHODCALLTYPE ThreadProc(
  void* pvTaskData,
  HANDLE hExitThreadEvent,
  HANDLE hNotifyEvent,
  HWND hwndWorker,
  volatile const BOOL* pfContinueProcessing
) = 0;

Parameters

• pvTaskData
  [in] Pointer to task data. This data is the same as that passed to ISpTaskManager::CreateThreadControl.
• hExitThreadEvent
  [in, out] Handle to event indicating that the thread process should exit.
• hNotifyEvent
  [in] Handle to an auto-reset event that will be set if the ISpThreadControl::NotifyEvent method is called. This parameter applies to any notification event the client determines, or it can optionally be ignored.
• hwndWorker
  [in] Window handle. This parameter is NULL if the caller of ISpThreadControl::StartThread passed in a null pointer to a window handle.
• pfContinueProcessing
  [in] Pointer to a value indicating if processing should continue. Set this value to TRUE to continue processing, and to FALSE otherwise. This parameter is set to reflect the input setting of hExitThreadEvent.
