Implement this method to execute code when the handle associated with this object becomes signaled.

HRESULT Execute(
   DWORD_PTR dwParam,
   HANDLE hObject 
);

Параметры

dwParam
The user parameter.
hObject
The handle that has become signaled.

Возвращаемое значение

Return S_OK on success, or an error HRESULT on failure.

Заметки

The handle and DWORD/pointer passed to this method were previously associated with this object by a call to CWorkerThread::AddHandle.

Пример

The following code shows a simple implementation of IWorkerThreadClient::Execute.

HRESULT Execute(DWORD_PTR dwParam, HANDLE hObject)
{
   // Cast the parameter to its known type.
   LONG* pn = reinterpret_cast<LONG*>(dwParam);

   // Increment the LONG.
   LONG n = InterlockedIncrement(pn);

   // Log the results.
   printf_s("Handle 0x%08X incremented value to : %d\n", (DWORD_PTR)hObject, n);

   return S_OK;
}
