[Warning: UMDF 2 is the latest version of UMDF and supersedes UMDF 1. All new UMDF drivers should be written using UMDF 2. No new features are being added to UMDF 1 and there is limited support for UMDF 1 on newer versions of Windows 10. Universal Windows drivers must use UMDF 2. For more info, see Getting Started with UMDF.]
The Complete method completes an I/O request.
void Complete(

Instead of calling Complete, the driver can call the IWDFIoRequest::CompleteWithInformation method.
For more information about completing an I/O request, see Completing I/O Requests.
The following code example completes a request with the failure that occurred when a memory object could not be retrieved.
IWDFIoRequest* FxRequest;
HRESULT hr = S_OK;
IWDFMemory* FxInputMemory = NULL;
FxRequest->GetInputMemory(&FxInputMemory);
if (S_OK != hr) {
FxRequest->Complete(hr);
}
