View source for Unwind

An '''unwind''' is an operation on a [[call stack]] in which the [[stack frame]]s of [[subroutine|procedure]] invocations on the call stack are discarded (i.e. those invocations are terminated) in order to return to an invocation higher up the [[stack]].

This is usually performed to allow a [[condition handler]] in a procedure instance further up the stack to run, to handle an [[exception]].
