How to customize the code interface of a function generated of a reference model

I was working on a code-generation project with a top model and several referenced models. I found it very easy to customize the name and argument of any entry-point functions in top model after following the link:

https://www.mathworks.com/help/ecoder/examples/specifying-function-prototypes-for-models.html

However, I could not find where to customize the function interfaces for referenced models. One of the referenced model I have takes a single input and return a single output, and the generated code has the function like:

void foo(const real_T *input, real_T *output);

I want it to be configured as:

real_T foo(const real_T input);

Could anyone give me some guidance?

Much appreciated!

Dear Boru,

If you have Embedded Coder, it is possible to control the entry points using the Function Prototype Control feature (https://www.mathworks.com/help/ecoder/ug/function-prototype-control.html). Basically, you can specify a new name for the "step" function, and each of the root-level ports become function arguments or return values. You can also specify smaller details about these arguments, such as adding "const" or making them pass-by-value or pass-by-reference.

TLC (Target Language Compiler) files are used to customize the code building process. They generally come in two varieties

1. System/model tlc files that help in the overall model conversion process
2. Block level tlc files which describe how individual blocks (typically S-Functions) get converted to C code.

For more details about TLC Compiler, you can refer to http://www.mathworks.com/help/releases/R13sp2/pdf_doc/rtw/targetlanguagecompiler.pdf
