From 0294a182a1629b1d854b84906e73487d6cb75fba Mon Sep 17 00:00:00 2001 From: Ed Schouten Date: Sat, 30 Apr 2011 10:55:14 +0000 Subject: Import a stock copy of ncurses 5.8 into the vendor space. It seems both local changes we made to 5.7 have already been fixed upstream properly, so there is no need to preserve the changes. Also, with SVN we import full source trees. Unlike CVS, where we removed unneeded cruft. --- test/test_addwstr.c | 516 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 516 insertions(+) create mode 100644 test/test_addwstr.c (limited to 'test/test_addwstr.c') diff --git a/test/test_addwstr.c b/test/test_addwstr.c new file mode 100644 index 000000000000..92334aee3b16 --- /dev/null +++ b/test/test_addwstr.c @@ -0,0 +1,516 @@ +/**************************************************************************** + * Copyright (c) 2009,2010 Free Software Foundation, Inc. * + * * + * Permission is hereby granted, free of charge, to any person obtaining a * + * copy of this software and associated documentation files (the * + * "Software"), to deal in the Software without restriction, including * + * without limitation the rights to use, copy, modify, merge, publish, * + * distribute, distribute with modifications, sublicense, and/or sell * + * copies of the Software, and to permit persons to whom the Software is * + * furnished to do so, subject to the following conditions: * + * * + * The above copyright notice and this permission notice shall be included * + * in all copies or substantial portions of the Software. * + * * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS * + * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF * + * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. * + * IN NO EVENT SHALL THE ABOVE COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, * + * DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR * + * OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR * + * THE USE OR OTHER DEALINGS IN THE SOFTWARE. * + * * + * Except as contained in this notice, the name(s) of the above copyright * + * holders shall not be used in advertising or otherwise to promote the * + * sale, use or other dealings in this Software without prior written * + * authorization. * + ****************************************************************************/ +/* + * $Id: test_addwstr.c,v 1.6 2010/12/12 00:18:00 tom Exp $ + * + * Demonstrate the waddwstr() and wadd_wch functions. + * Thomas Dickey - 2009/9/12 + * + * Note: to provide inputs for *add_wch(), we use setcchar().
