From 024704b60f04c4eada240315983424969530a9f7 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Diego=20=27Flameeyes=27=20Petten=C3=B2?= Date: Wed, 14 Nov 2007 00:20:36 +0100 Subject: Replace xine_private_strndup() implementation with NetBSD version. As the source file for xine_private_strndup() does not provide a licence header, replace it with a safe copy (licence wise) taken from NetBSD CVS. The implementation is licensed under 3-clause BSD licence, that is compatible with GPL-2 or later. --- lib/strndup.c | 60 +++++++++++++++++++++++++++++++++++++++++++++++++---------- 1 file changed, 50 insertions(+), 10 deletions(-) diff --git a/lib/strndup.c b/lib/strndup.c index 9f347db87..1e01aa018 100644 --- a/lib/strndup.c +++ b/lib/strndup.c @@ -1,16 +1,56 @@ +/* $NetBSD: strndup.c,v 1.4 2007/07/03 12:11:09 nakayama Exp $ */ + +/* + * Copyright (c) 1988, 1993 + * The Regents of the University of California.
