    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.
    int main() {
    int a = 0;
    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.

    void foo(int * 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);
