Number of active alarms in a specific area

Hello,

How canI write a script to count the number of active alarms in a specific area?

I already found a script which counts the total number of activealarms (from all defined areas).

DWORD dwMsgService, dwMsgs;
MSRTStartMsgService( &dwMsgService, NULL, NULL, 0, NULL, NULL );
MSRTGetMsgActual( &dwMsgs, NULL );
MSRTStopMsgService( dwMsgService, NULL );
SetTagWord("TagName",dwMsgs);

Maybe some of the aboveparameters cancan solve my problem? Where can I find a detailed description of the above functions?

Best regards,
Claudiu
