Where should I call Free() function?

Question

For example:

---

In A.c :

Head init(){
Head treeHead;
treeHead = malloc(sizeof (struct TreeHead));
treeHead->Root = malloc(sizeof (struct TreeNode)         


        

Answer 1

I would define a function in A.c:

void freeHead(Head head){
   free(head->Root);
   free(head);
   return;
}

Then call it in appropriate places in B.c:

freeHead(head);
