The common cases of adding a member to a linked list, and destroying the 
linked list along with the object:

struct list {
  int a, b, c;
  struct list* next;
};

void add_to_list(struct list* l, int a, int b, int c)
{
  struct list* n = malloc(sizeof(struct list));
  memset(n, 0, sizeof(struct list));
  n->a = a;
  n->b = b;
  n->c = c;
  n->next = l->next;
  l->next = n;
}

void destroy_list(struct list* l)
{
  struct list* n = 0;
  for(; l; l = n) {
    n = l->next;
    free(l);
  }
}

These two functions would be used as helpers by the datafile loading and 
unloading code, and are the main helpers for when you want to alter an 
object's properties. Of course, by making the linked list public, 
people can also do other stuff such as removing certain elements, etc.

Bye for now,
