C code to S function

I want to convert a peace of C-code from the huge chunk of code, into a MATALB S-function. Please let me know how to do it?

I have one function named 'FreezeCleaning' which is using some other sub functions and those are defined in diffrent files. Also, most of the variable type deifnation defined in different .h file.

How to create S function for this particular function including other sub functions and defincations?
