  36  * @brief Replacement of text output for Windows CE.
  37  *
  38  * This class allows standard text output to be displayed on
  39  * text window for Windows CE.  Generally, all ACE output will
  40  * go through under CE if and only if user uses Windows CE
  41  * implementation by using main_ce instead of main.
  42  * Also, for the easier debugging purpose, object pointer of
  43  * this class can be gotten from ACE_Log_Msg::msg_callback()
  44  * and then can be used directly by user just like cout stream.
