From 9dc2cbdeccdee432cd9bcdf8501f52e0f1d0e01b Mon Sep 17 00:00:00 2001 From: Guy Harris Date: Sun, 19 Feb 2012 05:57:14 +0000 Subject: Move dftest.c back to the top-level directory; that way, all of the stuff in ui/cli can be stuffed into a libcliui library to link with TShark, and all of the source files containing main() (except for Wireshark) are in the top-level directory (dftest isn't any more special than TShark or capinfos or mergecap or editcap or...). svn path=/trunk/; revision=41064 --- dftest.c | 199 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 199 insertions(+) create mode 100644 dftest.c (limited to 'dftest.c') diff --git a/dftest.c b/dftest.c new file mode 100644 index 0000000000..939f77be11 --- /dev/null +++ b/dftest.c @@ -0,0 +1,199 @@ +/* dftest.c + * Shows display filter byte-code, for debugging dfilter routines. + * + * $Id$ + * + * Wireshark - Network traffic analyzer + * By Gerald Combs + * Copyright 1998 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.
