From b51f157bff8b959d943b0836a1c57f065b9318d5 Mon Sep 17 00:00:00 2001 From: msmith Date: Sat, 21 Aug 1999 06:24:40 +0000 Subject: Implement a new generic mechanism for attaching handler functions to events, in order to pave the way for removing a number of the ad-hoc implementations currently in use. Retire the at_shutdown family of functions and replace them with new event handler lists. Rework kern_shutdown.c to take greater advantage of the use of event handlers.
