[CONNECT C++] Set Annotation Scale for Model

In V8i, I used to do:

// apply the new scale
SheetDef *pSheetDefNew = NULL;
pSheetDefNew = mdlSheetDef_new ();  //create a new blank to populate
mdlSheetDef_setScaleFactor (pSheetDefNew,SHEET_SCALE_TYPE_ANNOTATION_SCALE, iScale );
mdlModelRef_setSheetDef ( mdlModelRef_getActive (),pSheetDefNew);
mdlSheetDef_free (&pSheetDefNew);

But, there is no more mdlSheetDef_setScaleFactor(). What to do now?
