Hello every one,
is is possible that i call a c program from a stateflow chart, then I copy this chart, still in this same model, and execute both with out any conflict?
for example a C program like this
int var; // var is global
int myfunction(int n)
{
var = var + n;
return var;
}
i mean, treat them like two different entities and won't mess up with global variable.

btw, also without rename the function in source code, I've got a big program :)

Yes, you can create s functions of your legacy C code that can be used in your simulink model. To do this the easiest way is to use the legacy code tool. This tool will allow you to create an s function compile it and create a block that can be used in your model. Here is the link to the documentation.

Hello,
I observe that if I use just stateflow block matlab also create s function, do you think they are same?

Also you can integrate your C code directly in Stateflow chart for Simulation.
Check "Call Custom C Code Functions" on this page.
