| // Details: MI common code class. Specific OS stdin handling implementation. |
| // CMICmnStreamStdin instance is set with stdin handler before using the |
| // the stream. An instance of this class must be set up and ready to give |
| // to the CMICmnStreamStdin before it initialises other CMICmnStreamStdin |
| // will give an error. |
