pointers and function calls inside a function

Hello, I have a problem I am trying to figure out. I have a variable a in main. I am passing the address of this variable to my function foo.

Code:

---

int main() {
int a = 0;

foo(&a);

}

void foo(int * a);

---

in my function foo, I would like to do the same thing to this variable within my function foo, passing it to my function foo2.

Code:

---


void foo(int * a) {
 
  foo2(&(*a));

}

void foo2(int * a) {

  int x = *a;

}

---

would that be a proper call, parameter list and use of the variable in my function? thank you.

Actually since a inside foo is already a pointer you could just pass it along as foo2(a);
