What is purpose of the "rtmGetU" define in the Simulink Embeded Coder generated C code

Question

I have Simulink Embedded Coder output model code. One of header file includes;

#ifndef rtmGetU
#define rtmGetU(rtm) ((rtm)->ModelData.inputs)
#endif

After saw the code block in the header, I tried to generate my own Simulink model embedded code but the output not include the rtmGetU define.

I wonder what is the purpose of the rtmGetU define and how can I generate the rtmGetU code for my own model.

rtmGetU is a macro for conveniently getting the data that is being fed into any Inports in the model that the code is generated from.

It will only be in the generated code if your model has any Inports (at the highest level of the model.)
