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.

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.
