+ * The  system  service  occupies  the  alarm  <AlarmID>  element.
+ * When <start> ticks are reached, the task assigned to the alarm
+ *
+ * If the absolute value <start> is very close to the current counter
+ * value, the alarm may expire, and the task may become ready or
+ * the  alarm-callback  may  be  called  before  the  system  service
+ * returns to the user.
+ * If  the  absolute  value  <start>  already  was  reached  before  the
+ * system call, the alarm shall only expire when the absolute value
+ * <start>  is  reached  again,  i.e.  after  the  next  overrun  of  the
+ * counter.
+ *
+ * If <cycle> is unequal zero, the alarm element is logged on again
+ * immediately after expiry with the relative value <cycle>.
+ *
+ * The alarm <AlarmID> shall not already be in use.
+ * To  change  values  of  alarms  already  in  use  the  alarm  shall  be
+ * cancelled first.
+ *
+ * If  the  alarm  is  already  in  use,  this  call  will  be  ignored  and  the
+ * error E_OS_STATE is returned.
+ *
+ * Allowed on task level and in ISR, but not in hook routines.
