Thread: Simple Queue Question

Hi,

I'm trying to create a simple queue structure and am running into problems when I try to empty the queue. Here's the relevant pieces of code:

Code:

typedef struct queue_item {
   void *item;
   struct queue_item *next;
} q_item;

...
...

void GenericQueue::empty(q_item *i)
{
    if (i != NULL) {
        empty(i->next);
        free(i);
    }
}

It's all very simple but with Visual C++ I get an undefined heap error on the "free(i)" line. I thought I understood the basics of memory management but obviously not...can anyone point out my mistake?

Thanks,
Rob
