Replace simulink sincos block with embedded optimized simultaneous sin/cos function (Code Replacement Library)

I want the simulink block sincos to map to my microcontroller optimized simultaneous sin and cosine routine. The C function is:

void sincos(float32 radian, float32* PtrSin, float32* PtrCos);

Is there a problem in that the function return is void, and that the results are returned as pointers in the function arguments? Do I need to use createAndAddConceptualArg, createAndSetCImplementationReturn, and createAndAddImplementationArg? If so, what parameters should I pass to these matlab functions?

Thanks
