void 
  GetFileObject(
    OUT IWDFFile**  ppFileObject
    );

Parameters

A pointer to a buffer that receives a pointer to the IWDFFile interface for the file object. Note that returning NULL is valid.

Example

The following code example verifies if a request's file object matches the file object that the caller provides and, if so, performs cleanup processing for the request:

  IWDFIoRequest request;
  IWDFFile *MatchFile;

  IWDFFile *fxFile;

  request->GetFileObject(&fxFile);

  if (MatchFile == fxFile) {
      Device->CancelRequest(request, TRUE);
  }
