Complete Instrument Information List

The complete instrument information list contains a list of all atomic instruments supported by an instrument component. It is defined by the InstCompInfo data type.



 
struct InstCompInfo {

    long                        infoSize;

    long                        GMinstrumentCount;

    GMInstrumentInfoHandle      GMinstrumentInfo;

    long                        GMdrumCount;

    GMInstrumentInfoHandle      GMdrumInfo;

    long                        nonGMinstrumentCount;

    nonGMInstrumentInfoHandle   nonGMinstrumentInfo;

    long                        nonGMdrumCount;

    nonGMInstrumentInfoHandle   nonGMdrumInfo;

};
