  38 /*  FUNCTION
  39         This function will shut down the operating system.
  40
  41     INPUTS
  42         action - what to do:
  43          * SD_ACTION_POWEROFF   - power off the machine.
  44          * SD_ACTION_COLDREBOOT - cold reboot the machine (not only AROS).
  45
  46     RESULT
  47         This function does not return in case of success. Otherwise is returns
  48         zero.
  49
  50     NOTES
  51         It can be quite harmful to call this function. It may be possible that
  52         you will lose data from other tasks not having saved, or disk buffers
  53         not being flushed. Plus you could annoy the (other) users.
