From 669db206cb1f270046ad400fff7655e20c63e723 Mon Sep 17 00:00:00 2001 From: Gilbert Ramirez Date: Sun, 18 Jul 2004 18:06:47 +0000 Subject: Move dissectors to epan/dissectors directory. Also move ncp222.py, x11-fields, process-x11-fields.pl, make-reg-dotc, and make-reg-dotc.py. Adjust #include lines in files that include packet-*.h files. svn path=/trunk/; revision=11410 --- epan/dissectors/packet-cosine.c | 193 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 193 insertions(+) create mode 100644 epan/dissectors/packet-cosine.c (limited to 'epan/dissectors/packet-cosine.c') diff --git a/epan/dissectors/packet-cosine.c b/epan/dissectors/packet-cosine.c new file mode 100644 index 0000000000..2c8fa84666 --- /dev/null +++ b/epan/dissectors/packet-cosine.c @@ -0,0 +1,193 @@ +/* packet-cosine.c + * Routines for decoding CoSine IPNOS L2 debug output + * + * $Id$ + * + * Motonori Shindo + * + * Ethereal - Network traffic analyzer + * By Gerald Combs + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License + * as published by the Free Software Foundation; either version 2 + * of the License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
