How to programmatically get input and output types for C code generation in Matlab Coder?

I want to write custom initialization and termination functions in Matlab Coder for C source code generation. I know that I could either use the codegen functionality of using CustomInitializer or CustomTerminator or the Matlab Coder App "Custom Code" tab.

I want to use the input and output variables to the main entry point in codegen or Matlab Coder in the initializer and terminator functions. How could I do that to build a custom toolchain?

Can you please explain your usecase with a simple example ?

Are you looking to access the type of the gnerated functions in C ( like int,float etc ) ?

The output types are actually inferred from the input types during codegen, so it may not be possible to access them before hand.

You can check the documentation of coder.getArgsType() and see if that helps your usecase :

Thanks for replying.

Yes, I want to access the type and variable names of the generated C function's input and outputs.

The use-case is the following:

I want to use these variable types and names to initialize them in an initializer function or use the output in a terminator function.

I was also thinking of using the global variables to do that. Is it possible to get the global variable name and types and use them in some way in the initializer or terminator function?
