Sending a dummy variable to a function as a compound literal

Let's say I have the following I'm using to call a function:

Item dummy;  while (!QueueIsEmpty(pq))      DeQueue(pq, &dummy);  

Is there a way to put the dummy parameter into the call itself? Something like:

while (!QueueIsEmpty(pq))      DeQueue(pq, &(Item)NULL);
