Change Simulink function exported prototype

Hi,

I'm trying to generate a set of public functions that will serve as interface to my module once I generate C code from it. I'm setting up a number of Simulink Functions in the top level of that model and in general it works as intended.

The only problem is that I can't control the function naming once the C file gets generated. It always generates it in the format of ModuleName_FunctionName(args), but the coding guidelines from the company I work for state that we must use ModuleName__FunctionName(args), with the double underscore.

How can I achieve this? I'm sending attached a sample model with a single Simulink function.

Are you using Simulink Function Block ?

Which Matlab Version?

In my Matlab 2015b, I can easily control the function name (file name is always same as function name) in Simulink Function Block.

Hi Tabrez, I'm using 2018a. I used to be able to control it easily with 2017a as well, but can't find that same option in the latest release.
