This service call returns various statuses of the alarm handler indicated by almid.
almstat
The status of the target alarm handler is returned.
*TALM_STA Alarm handler is an operational state.
*TALM_STP Alarm handler is a non-operational state.
lefttim
The remaining time before the target alarm handler will start next is returned. This time is expressed in ms units.
If the target alarm handler is a non-operational state, the returned value is indeterminate.
If this service call is to be issued from task context, use ref_alm; if issued from non-task context, use iref_alm.
