AlarmQueryFirstRec
Searches for the first occurrence of an alarm category (or priority) and type. This is a wrapper function of AlarmFirstCatRec and AlarmFirstPriRec.
When the Alarm Server is not in the calling process, this function will become blocking and cannot be called from a foreground task. In this case, the return value will be undefined and a Cicode hardware alarm will be raised.
