Date: Mon, 24 Mar 2003 02:22:01 +0100 From: Jens Rehsack <rehsack@liwing.de> To: audit@freebsd.org Cc: Tom Rhodes <trhodes@FreeBSD.org>, Harti Brandt <harti@freebsd.org> Subject: 1st new patch for src/sbin/atm/ilmid/ilmid.c Message-ID: <3E7E5DB9.7020406@liwing.de>
index | next in thread | raw e-mail
[-- Attachment #1 --]
Hi,
here is the 1st patch for src/sbin/atm/ilmid/ilmid.c as discussed with
Tom Rhodes. It contains only a declaration for each function which is
implemented (prototype) and fixes some errors resulting from the change.
I attach 2 patches: The first one is just the patch which declares the
prototypes and is informational only. The 2nd one fixes the errors the
compiler reports, too.
Hope this is a little better than last (big) one.
Jens
