From 321029f1c35db68c9d2e15408871030a36694541 Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Wed, 3 Mar 2010 02:11:46 -0800 Subject: sparc64: Fix msgrcv() msgrcv() does not work on sparc64, as it passes the 6th argument using the ipc kludge, while the kernel waits for a 6 arguments syscall. This patches fixes the problem by using a sparc64 specific version of msgrcv.c. 2010-03-03 Aurelien Jarno * sysdeps/unix/sysv/linux/sparc/sparc64/msgrcv.c: New file. --- sysdeps/unix/sysv/linux/sparc/sparc64/msgrcv.c | 49 ++++++++++++++++++++++++++ 1 file changed, 49 insertions(+) create mode 100644 sysdeps/unix/sysv/linux/sparc/sparc64/msgrcv.c (limited to 'sysdeps/unix/sysv/linux/sparc/sparc64/msgrcv.c') diff --git a/sysdeps/unix/sysv/linux/sparc/sparc64/msgrcv.c b/sysdeps/unix/sysv/linux/sparc/sparc64/msgrcv.c new file mode 100644 index 0000000000..117762c779 --- /dev/null +++ b/sysdeps/unix/sysv/linux/sparc/sparc64/msgrcv.c @@ -0,0 +1,49 @@ +/* Copyright (C) 2010 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 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.
