non simple mutex


pthread_t tid[2];
int counter;

void* doSomeThing(void *arg)
    unsigned long i = 0;
    counter += 1;
    printf("\n Job %d started\n", counter);

    for(i=0; i<(0xFFFFFFFF);i++); //this is just wait
    printf("\n Job %d finished\n", counter);

    return NULL;

int main(void)
    int i = 0;
    int err;

    while(i < 2)
        err = pthread_create(&(tid[i]), NULL, &doSomeThing, NULL);
        if (err != 0)
            printf("\ncan't create thread :[%s]", strerror(err));

    pthread_join(tid[0], NULL);
    pthread_join(tid[1], NULL);

    return 0;
