From cdb3c81f36283df4b53f24a374d78c695e9d8b06 Mon Sep 17 00:00:00 2001 From: Eric Andersen Date: Mon, 17 Jun 2002 21:12:16 +0000 Subject: Re-backport all the rpc stuff from glibc 2.2.5. This allows us to make this junk (and I do mean that ;-) thread safe without undue pain. Adds 12k worth to the code size I'm afraid, but since I never use NFS and therefore never include this stuff, I guess thats acceptable. I still need to enable the multi-threaded bits... -Erik --- libc/inet/rpc/xdr_intXX_t.c | 203 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 203 insertions(+) create mode 100644 libc/inet/rpc/xdr_intXX_t.c (limited to 'libc/inet/rpc/xdr_intXX_t.c') diff --git a/libc/inet/rpc/xdr_intXX_t.c b/libc/inet/rpc/xdr_intXX_t.c new file mode 100644 index 000000000..d36d1623b --- /dev/null +++ b/libc/inet/rpc/xdr_intXX_t.c @@ -0,0 +1,203 @@ +/* Copyright (c) 1998, 1999, 2000 Free Software Foundation, Inc. + This file is part of the GNU C Library. + Contributed by Thorsten Kukuk , 1998. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 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.
