From 181b716d654861e688a0b2e97c5467df3e6d5c5c Mon Sep 17 00:00:00 2001
From: Roland McGrath <roland@gnu.org>
Date: Sat, 31 Mar 2001 23:09:21 +0000
Subject: 2001-03-29 Neal H Walfield <neal@cs.uml.edu>
* host.c: Fix comments.
(ps_host_basic_info): Make INITIALIZED static; otherwise
we never cache BUF. Do not initalize static variables to 0.
(ps_host_sched_info): Likewise.
* ps.h: Doc fix.
