How to know if a function is called in C with or without typecasting using gdb or any other tool?

I have a lib from which a function is called using function pointer, the function pointer is set by us in local code.

The issue is, i have assigned the pointer an address of a function which accepts arguments.

and i am suspecting that in lib the function is called without arguments i.e. after type casting it to some other type.

Now, i want to know by using gdb or any other tool weather the function is called with/without type cast. I do not have exact code for the lib but i do have the lib with debug flags.

To explain here is a code snippet:

typedef  int (*type1)(void);
typedef int (*type2)(int, int);

int calledFunc (int,int);

int main(int argc, char *argv[])
{
    type1 t1;

    t1 = (type1)&calledFunc;

   t1();

   ((type2)t1)(5,6);

  system("PAUSE");  
  return 0;
}

int calledFunc (int a, int b)
{
    printf("Function called=> %d\n",a+b);
    return (a+b);
}

In above code how we can deduce using gdb if CalledFunc is called with or without typecasting?
