Variable Font and FT_Load_Sfnt_Table

Hi,

If variable font is set using FT_Set_Var_Design_Coordinates(ftFace, ... ) or FT_Set_Named_Instance(ftFace, ...) and then call to FT_Load_Sfnt_Table(ftFace,...) is made, does it return table data specific to variation set on ftFace or whole data of variable font ?

Any help is appreciated ?

Thanks
