Consider the following program that uses the standard Pthreads API:

 #include  #include  #include  

 #define NUMBER_OF_THREADS 10 

void *print_hello_world(void *tid) {

/* This function prints the threads identifier and then exits. */ printf("Hello World. Greetings from thread %d ", tid); pthread_exit(NULL);

}

 int main(int argc, char *argv[]) { 

/* The main program creates 10 threads and then exits. */ pthread_t threads[NUMBER_OF_THREADS]; int status, i;

for(i=0; i < NUMBER_OF_THREADS; i++) {

printf("Main here. Creating thread %d ", i); status = pthread_create(&threads[i], NULL, print_hello_world,

(void *)i);

 if (status != 0) { 

printf("Oops. pthread_create returned error code %d ", status)

exit(-1);

}

}

 exit(NULL); } 

The thread creations and messages printed by the threads are interleaved at random. Is there a way to force the order to be strictly thread 1 created, thread 1 prints message, thread 1 exits, thread 2 created, thread 2 prints message, thread 2 exists, and so on? If so, how? If not, why not?
