Thread: Problem when concatenating two dynamic queues

I have a Queue *q1, *q2 in main() that I send off the a function to initialize that looks like this:

Code:

Queue *CreateQueue () {
   Queue *queue;

   queue->front = queue->rear = NULL;

   return queue;
}

Doesn't this create a brand new Queue, initialize it to NULL, then return it back to the calling function?

But what happens is that when I manipulate one queue, the exact same operation is performed on the other queue, as if they were the same queue.

From my other thread asking for queue help (http://cboard.cprogramming.com/showthread.php?t=57999), itsme86's queue initialization works fine because it creates QUEUE q1, q2; in main () before sending it off to be initialized:

Code:

void new_queue(QUEUE *q)
{
  q->head = q->tail = NULL;
}

Why doesn't my method work?

Doesn't calling the function to to create a new variable make it separate from one that was created in a previous call? What I'm doing is basically this:

Code:

main()
{
   // .........

   Queue *q1 = CreateQueue(q1);
   Queue *q2 = CreateQueue(q2); //why isn't this new q2 separate from q1?
}

I then malloc when I append an item onto the queue.
