IOCTL_CHANGER_INITIALIZE_ELEMENT_STATUS IOCTL

Initializes the status of all elements or the specified elements of a particular type.

To perform this operation, call the DeviceIoControl function with the following parameters.

C++
BOOL DeviceIoControl(
  (HANDLE) hDevice,                        // handle to device
  IOCTL_CHANGER_INITIALIZE_ELEMENT_STATUS, // dwIoControlCode(LPVOID) lpInBuffer,                     // input buffer
  (DWORD) nInBufferSize,                   // size of input buffer
  NULL,                                    // lpOutBuffer0,                                       // nOutBufferSize(LPDWORD) lpBytesReturned,               // number of bytes returned
  (LPOVERLAPPED) lpOverlapped              // OVERLAPPED structure
);
