Implement this method to execute code when the handle associated with this object becomes signaled.
HRESULT Execute(
DWORD_PTR dwParam,
HANDLE hObject
);
Parameters
dwParam
The user parameter.hObject
The handle that has become signaled.
Return Value
Return S_OK on success, or an error HRESULT on failure.
Remarks
The handle and DWORD/pointer passed to this method were previously associated with this object by a call to CWorkerThread::AddHandle.
Example
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;
}
