From 7163e69e10f3bbbe71a416d15e66eac16c852d27 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sun, 28 May 2000 18:32:20 +0000 Subject: Update. 2000-05-21 Jakub Jelinek * libio/libioP.h (_IO_CHECK_WIDE): Define. * libio/iosetbuffer.c (_IO_setbuffer): Use it. Call _IO_WSETBUF even for _mode 1. * libio/iosetvbuf.c (_IO_setvbuf): Likewise. * libio/fileops.c (_IO_new_file_fopen): Return NULL if _IO_CHECK_WIDE fails. --- libio/bits/stdio.h | 2 +- libio/fileops.c | 6 ++++-- libio/iosetbuffer.c | 6 +++--- libio/iosetvbuf.c | 7 ++++--- libio/libioP.h | 2 ++ 5 files changed, 14 insertions(+), 9 deletions(-) (limited to 'libio') diff --git a/libio/bits/stdio.h b/libio/bits/stdio.h index d698132558..2522a3846e 100644 --- a/libio/bits/stdio.h +++ b/libio/bits/stdio.h @@ -1,5 +1,5 @@ /* Optimizing macros and inline functions for stdio functions. - Copyright (C) 198 Free Software Foundation, Inc. + Copyright (C) 1998, 2000 Free Software Foundation, Inc.
