Deleting linked lists.

[Byron Warner]

I was wondering, is it safe to unallocate a singly linked list like this:

struct list *head; /* top of list */
struct list *ptr = head;
while (ptr){
	free(ptr);
	ptr = ptr->next;
}

I am not sure if I can assume that
the value of ptr will not be corrupted
after it is freed.
