Deallocate not working for me - wallace - 02-20-2006
I'm sure that I'm just using it wrong:
Code:
Sub DestroyLinkedList(l as LinkedList)
dim p as ListElement ptr
dim c as ListElement ptr
p = l.Head
do while( p <> 0)
c = p
p = p->enext
deallocate c 'remove list element
loop
deallocate @l 'remove last traces of list
End SubWhen I call my PrintLinkedList sub, it shows that nothing was removed.

This doesn't mean that your memory has not been deallocated. All your pointers still point to the same places in memory, and nothing has been overwritten yet. Deallocating memory alerts your memory manager that it can use that memory in a future memory allocation.

You can always set the pointers to NULL after deallocating as well. It's what I do, though I'm not sure that it's necessary. :wink:

Oh, so it is working. Thanks.
