From 9aed53cc26d900ab64f49c38df535cf10518aa51 Mon Sep 17 00:00:00 2001 From: Manuel Novoa III Date: Thu, 1 Mar 2001 19:49:41 +0000 Subject: Added __strtok_r function. Change strtok to a wrapper around __strtok_r and add a weak alias of __strtok_r for strtok_r since optional. Also reduced code size. --- libc/string/strtok.c | 61 +++------------------------------------------------- 1 file changed, 3 insertions(+), 58 deletions(-) (limited to 'libc/string/strtok.c') diff --git a/libc/string/strtok.c b/libc/string/strtok.c index 51bc6038a..9dc19a90b 100644 --- a/libc/string/strtok.c +++ b/libc/string/strtok.c @@ -1,63 +1,8 @@ -/* Copyright (C) 1991 Free Software Foundation, Inc. -This file is part of the GNU C Library. - -The GNU C Library is free software; you can redistribute it and/or -modify it under the terms of the GNU Library General Public License as -published by the Free Software Foundation; either version 2 of the -License, or (at your option) any later version. - -The GNU C Library 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.
