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.
