IOCTL_CHANGER_SET_POSITION IOCTL (winioctl.h)

  • Article

Sets the changer's robotic transport mechanism to the specified element address. This optimizes moving or exchanging media by positioning the transport beforehand.

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

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