C: Increase the value of variable in the recursive function without using global or static variable?

Question

I have a recursive function as below,

void func()
{
       if(counter>10)
              return;
       func();
}

Here, I need to come out of the function when counter reaches specific number(10 as per example).
Now, the condition is, I can't take this counter as global or static or can't pass this counter as parameter.

Any suggestion to solve this given above terms.
