Modeling of a legacy code

Hello,

I have a question about simulink modeling of a legacy code.

Let's assume that i have a legacy code as below in one file.

[test.c]

static single a=0.;
static single b=0.;

void FcnA(single ain, single *aout)
{
     a = ain;
     *aout = a;
}

void FcnB(single bin, sinlge *bout)
{    
      b = a * bin;
      *bout = b;
}

I would like to integrate the legacy code above in simulink without modifying the code.

I can use the legacy code tool to model the code but the problem is that FcnB does not use the variable 'a' as an input argument. So i cannot think of any way to integrate the code in simulink.

Is there a good way to do it?

coder.ceval(), possibly the second example if the code is already compiled into a single library.
