How do I group signal definitions per their data types in generated code?

I am generting C code from a model which contains signals with different data types like integers, characters, words etc.

When generating code, I would like to group signal definitions all signals of same type together.

Foe example:

unit8 var1; uint8 var4;

uint16 var2; uint16 var3;

uint32 var5;

How can I achieve this?

The class() function can reveal what type of data is being input. To sort it you could check the class of the input and store it in a vector. This code is assuming your "input" is from an outside source so this is treated like a separate function call. If the input is internal then you could also use a for-loop around the switch-case

global array8 array16 array32
input = uint8(12);
switch class(input)
case 'uint8'
  array8(end+1) = input;
case 'uint16'
  array16(end+1) = input;

etc.

that's just a demo, you'd have to include

 array8 = []

and stuff for that to be functional. If you're more specific we could help you out a bit better, but that should get you started :)

Thanks for the answer Jonathan. However, I would like these variables to be grouped directly in the generated C file.

So, if my model uses 3 UByte signals, 3 Uint signals , then when RTW generates C code I would like their declarations to be grouped together.
