From d052b31b79a3681db7de04177a55b04354320a61 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Fri, 21 Jul 2000 06:15:13 +0000 Subject: Update. * libio/Makefile (routines): Add fwide. * libio/iofwide.c (_IO_fwide): Remove locking. This is done in fwide now. Internal calls to _IO_fwide must do locking themselves or don't need locking. * libio/fwide.c: New file. * elf/dl-load.c (_dl_map_object): Implement handling of DF_1_NODEFLIB. --- libio/fwide.c | 53 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 53 insertions(+) create mode 100644 libio/fwide.c (limited to 'libio/fwide.c') diff --git a/libio/fwide.c b/libio/fwide.c new file mode 100644 index 0000000000..a4d0e4708c --- /dev/null +++ b/libio/fwide.c @@ -0,0 +1,53 @@ +/* Copyright (C) 1999, 2000 Free Software Foundation, Inc. + This file is part of the GNU IO Library. + + This library 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, or (at + your option) any later version. + + This 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.
