= D =
dangling pointer n.
[common] A reference that doesn't
actually lead anywhere (in C and some other languages, a pointer
that doesn't actually point at anything valid). Usually this
happens because it formerly pointed to something that has moved or
disappeared. Used as jargon in a generalization of its techspeak
meaning; for example, a local phone number for a person who has
since moved to the other coast is a dangling pointer. Compare
