Ejects media from a SCSI device.

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

C++
BOOL DeviceIoControl(
  (HANDLE) hDevice,            // handle to device
  IOCTL_STORAGE_EJECT_MEDIA,   // dwIoControlCodeNULL,                        // lpInBuffer0,                           // nInBufferSizeNULL,                        // lpOutBuffer0,                           // nOutBufferSize(LPDWORD) lpBytesReturned,   // number of bytes returned
  (LPOVERLAPPED) lpOverlapped  // OVERLAPPED structure
);
