  (LPVOID) lpInBuffer,                      // input buffer
  (DWORD) nInBufferSize,                    // size of input buffer
  NULL,                                     // lpOutBuffer
  0,                                        // nOutBufferSize
  (LPDWORD) lpBytesReturned,                // number of bytes returned
  (LPOVERLAPPED) lpOverlapped               // OVERLAPPED structure
