Searches for the first occurrence of an alarm category and type. You can search all areas, the current area only, or specify an area to limit the search.
This function returns an alarm record identifier that you can use in other alarm functions, for example, to acknowledge, disable, or enable the alarm, or to get field data on that alarm.
Note: Record numbers obtained from AlarmGetDsp are not valid for this function.
This is a blocking function. If the function is called from a foreground task that is unable to block, the return value will be -1 and a hardware alarm set. Use IsError() to retrieve the error code.
