CCS/K2GICE: Type unresolved symbol Log_write1 : what libruary to add

Part Number: K2GICE

Tool/software: Code Composer Studio

Hi

Im getting error: Type unresolved symbol Log_write1 with code where i would like to use UIABenchmarks. for code:

        Log_write1(UIABenchmark_start, (xdc_IArg)"running");
        while(i < 5000000) {
            X = (2*A - B - C)*sqr6;
            Y = (B - C)*sqr2;
            Z = (A + B + C)*sqr3;

            co = cosdp(theta);
            si = sindp(theta);

            D = co*X + si*Y;
            Q = co*Y - si*X;
            i++;
        }
        Log_write1(UIABenchmark_stop, (xdc_IArg)"running");

It seems like i need some libruary for the code, but i can not find out which one i need. Where is this information available?
