Hello, good helpers!

I got everything so far to go OK, but I am having trouble figuring out the 'function call' syntax.
I am sure it is simpler than what I'm used to, and that is why I can't figure it out ...

Let struct person be the way it was, name, addr, tlf.

>From C

/*
* Instantiate an object of type person.
* The name will be filled in, the rest will be default
* values (inherited?)
* The C way is to either build up structs or 
* pass in a subclass pointer
*/
struct person *new_person(char* name)
{
	struct person *prv; /* A dynamic reference? */

	prv = malloc(sizeof(struct person)); /* Create a dynamic instance? */
	if ( ! prv)
	{
		perror("malloc");
		return(0); /* Spoiled with automatic casting, should be (struct person*) 0 */
	}

	strcpy(prv->name, name); /* Person has this name from input parm */
	strcpy(prv->addr, sc->addr); /* Don't bother with this now */
	strcpy(prv->tlf, "000"); /* Call the police */

	return(prv); /* Imperative :-) that I understand enter and exit */
}

void person_set(struct person *p, char *name, char *addr, char* tlf)
{
	if (name)
		strcpy(p->name, name);
	
	if (addr)
		strcpy(p->addr, addr);

	if (tlf)
		strcpy(p->tlf, tlf);
}

int not_person_related(char *s)
{
	s[0] = 'X';
	return(12);
}

void main(int ac, char *av[])
{
	struct person *p;
	int x, y;
	char s[25];

	p = person_new("Newman");
	if ( ! p)
		exit(0);

	person_set(p, 0, "Hovden", "3716 8532");
/*-------- So far, so good. These are typically 'object' functions ---*/


/* But what with this?	*/

	x = not_person_related(s);
	x = not_person_related(p->tlf);		
}
