This service call returns various statuses of the cyclic handler indicated by cycid.
cycstat
The status of the target cyclic handler is returned.
*TCYC_STA Cyclic handler is an operational state.
*TCYC_STP Cyclic handler is a non-operational state.
lefttim
The remaining time before the target cyclic handler will start next is returned. This time is expressed in ms units.
If the target cyclic handler is non-operational state, the returned value is indeterminate.
If this service call is to be issued from task context, use ref_cyc; if issued from non-task context, use iref_cyc.
