How to add Get function to the Simulink model generated code

Hello,

I'm generation code from the Simulink model (2 inputs, three outpus). I'd like to add Get function for the output(s), e.g.:

RLS_OnOff LGTC_getRearLightOn(void)

{

return strVarRear.enuRearLightOn;

}

I tried it using Access Data Through Functions with Storage Class GetSet but not successfuly. In the Code Mapping, Data Defaults ribon, I updated Storage class for updates to the "GetSet". But during the code generation I received the folloiwng error message:

In model code mappings, default storage class for outports is set to 'GetSet', making generated code noncompliant with function prototype control feature. Set default storage class to 'Default'.

If I update it to Default to get rid of the error Get function is not created.

Does anybody know how to update the Code generation setting/code mapping to sucessfully build the model to get code containing the Get function for the output?

Thank you very much in advance
