Ejects media from a SCSI device.

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

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