Thank you very much! It works for  Array Data Pointer!

I used float array (Size: 16) and read  the first 3 values.

Thanks a lot!

This is the program. It can run to CL polling measure.vi

 libclapi.dlCL-500A.llb

Thank you very much for this kind reply.

I  tried this method (A Cluster that contains 3 SGL numbers, and use this cluster to to tell the CLFN how to interpret the data.).But it will show this error or the program crashed.

Trying to call the function below. I would like to read CL_MEASDATA information. Actually just need Evxy.

ER_CODE KMAPI CLGetMeasData(DEVICE_HANDLE hDevice, CL_COLORSPACE Type, CL_MEASDATA* pColor); 

typedef union tCL_MEASDATA

{

        CL_EvxyDATA           Evxy;                                       

        CL_EvuvDATA          Evuv;                                       

        CL_EvTduvDATA       EvTduv;                                   

        CL_EvDWPeDATA    EvDWPe;                                 

        CL_XYZDATA            XYZ;                                

        CL_RenderingDATA Rendering;                      

        CL_PWDATA            Pw;                                         

        CL_SPCDATA            Spc;                                 

}

CL_MEASDATA;
