What's the real order? Order in which friend threads were spawned or the ticket id that they came back with?

	#include <stdio.h>
	#include <stdlib.h>
	#include <pthread.h>

	static int ticketid = 0;
	pthread_mutex_t lock;

	// buyticket function remote dial a central store to obtain ticket id
	void * buyticket() {
	int id = (int )malloc(sizeof(int));
