I want to have the tint to the color information of the Cos Object.

Question

I have developed a plug-in now.
My plug-in is creating a color with a Cos Object.And, It is used to fill the art object.
I would like to have the information of tint to this color.
Please tell me how to have a tint.
--- The following is the code which creating a color. ---
    PDEColorSpace spotColorSpace;
    CosDoc cosDoc = PDDocGetCosDoc(pdDoc);
    char *functionText = "{50.0 -128.0 -128.0}";
    // Domain
    CosObj domain = CosNewArray(cosDoc, false, 2);
    CosArrayPut(domain, 0, CosNewFloat(cosDoc, false, 0.0f));
    CosArrayPut(domain, 1, CosNewFloat(cosDoc, false, 1.0f));
    // Range
    CosObj range = CosNewArray(cosDoc,false,6);
    CosArrayPut(range, 0, CosNewFloat(cosDoc, false, 0.0f));
    CosArrayPut(range, 1, CosNewFloat(cosDoc, false, 100.0f));
    CosArrayPut(range, 2, CosNewFloat(cosDoc, false, -128.0f));
    CosArrayPut(range, 3, CosNewFloat(cosDoc, false, 127.0f));
    CosArrayPut(range, 4, CosNewFloat(cosDoc, false, -128.0f));
    CosArrayPut(range, 5, CosNewFloat(cosDoc, false, 127.0f));
    // create dictionary
    CosObj tintTransform = CosNewDict(cosDoc, false, 4);
    CosDictPut(tintTransform,ASAtomFromString("FunctionType"),CosNewInteger(cosDoc,false,4));
    CosDictPut(tintTransform, ASAtomFromString("Domain"), domain);
    CosDictPut(tintTransform, ASAtomFromString("Range"), range);
    ASStm asStm = ASMemStmRdOpen(functionText, strlen(functionText));
    CosObj function = CosNewStream(cosDoc, true, asStm, 0, true, tintTransform, CosNewNull(), -1);
    ASStmClose(asStm);
    // create Lab
    PDEColorSpace altSpace = createLab(pdDoc);
    PDESeparationColorData data;
    data.alt = altSpace;
    data.name = ASAtomFromString("MyColor");
    data.size = sizeof(data);
    data.tintTransform = function;
    PDEColorSpaceStruct clrStruct;
    clrStruct.sep = &data;
    spotColorSpace = PDEColorSpaceCreate(ASAtomFromString("Separation"), &clrStruct);

Thank you for the reply.
Sorry... I forgot to write createLab() function.
I am trying to create a color in the separation color space.
I just have to set the lab to the AlternateSpace.
Please tell me how to make the separation color and how to have the tint to the separation color.
PDEColorSpace createLab(PDDoc pdDoc)
    PDEColorSpace labColorSpace;
    CosDoc cosDoc = PDDocGetCosDoc(pdDoc);
    // Lab
    CosObj csLab = CosNewArray(cosDoc, false, 2L);
    CosObj csLabDic = CosNewDict(cosDoc, false, 3L);
    // WhitePoint
    CosObj csWhitePoint = CosNewArray(cosDoc, false, 3);
    CosArrayPut(csWhitePoint, 0, CosNewFloat(cosDoc, false, 0.964203f));
    CosArrayPut(csWhitePoint, 1, CosNewFloat(cosDoc, false, 1.0f));
    CosArrayPut(csWhitePoint, 2, CosNewFloat(cosDoc, false, 0.824905f));
    CosDictPutKeyString(csLabDic, "WhitePoint", csWhitePoint);
    // Range
    CosObj csRange = CosNewArray(cosDoc, false, 4L);
    CosArrayPut(csRange, 0, CosNewFloat(cosDoc, false, -128.0f));
    CosArrayPut(csRange, 1, CosNewFloat(cosDoc, false, 127.0f));
    CosArrayPut(csRange, 2, CosNewFloat(cosDoc, false, -128.0f));
    CosArrayPut(csRange, 3, CosNewFloat(cosDoc, false, 127.0f));
    CosDictPutKeyString(csLabDic, "Range", csRange);
    // BlackPoint
    CosObj csBlackPoint = CosNewArray(cosDoc, false, 3);
    CosArrayPut(csBlackPoint, 0, CosNewFloat(cosDoc, false, 0.0f));
    CosArrayPut(csBlackPoint, 1, CosNewFloat(cosDoc, false, 0.0f));
    CosArrayPut(csBlackPoint, 2, CosNewFloat(cosDoc, false, 0.0f));
    CosDictPutKeyString(csLabDic, "BlackPoint", csBlackPoint);
    CosArrayPut(csLab, 0L, CosNewNameFromString(cosDoc, false, "Lab"));
    CosArrayPut(csLab, 1L, csLabDic);
    labColorSpace = PDEColorSpaceCreateFromCosObj(&csLab);
    return labColorSpace;
