If the prototype of my function is void sell_item(store **head,store **tail). In main i've passed sell_item(&head,&tail), where head & tail where both pointers of store(struct) type.

Now I want to access the the content where head is pointing to. How shall I access it? Like *head->next??? But this is not working.
where next is another member of store storing pointing to the next location of memory (pointing to next node).

head is a pointer to a pointer to a store.

So *head is a pointer to a store.

So *(*head) is a store.

So (*(*head)).next is the member variable next of the store.
