From 082e680bd54e999f2bb4eb77141958938b1e9ee9 Mon Sep 17 00:00:00 2001 From: Manuel Novoa III Date: Wed, 11 Feb 2004 23:48:50 +0000 Subject: New stdio core. Should be more maintainable. Fixes a couple of bugs. Codepaths streamlined. Improved performance for nonthreaded apps when linked with a thread-enabled libc. Minor iconv bug and some locale/thread related startup issues fixed. These showed up in getting a gcj-compiled java helloworld app running. Removed some old extension functions... _stdio_fdout and _stdio_fsfopen. --- libc/stdio/_load_inttype.c | 66 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 66 insertions(+) create mode 100644 libc/stdio/_load_inttype.c (limited to 'libc/stdio/_load_inttype.c') diff --git a/libc/stdio/_load_inttype.c b/libc/stdio/_load_inttype.c new file mode 100644 index 000000000..2dd559a53 --- /dev/null +++ b/libc/stdio/_load_inttype.c @@ -0,0 +1,66 @@ +/* Copyright (C) 2004 Manuel Novoa III + * + * GNU Library General Public License (LGPL) version 2 or later. + * + * Dedicated to Toni.
