  30          * SD_ACTION_POWEROFF   - power off the machine.
  31          * SD_ACTION_COLDREBOOT - cold reboot the machine (not only AROS).
  32

  35         zero.
  36
  37     NOTES
  38         It can be quite harmful to call this function. It may be possible that
  39         you will lose data from other tasks not having saved, or disk buffers
  40         not being flushed. Plus you could annoy the (other) users.
