From a894053318f1ca246d13bb9efa65bd702df6b63e Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Mon, 15 Mar 2021 15:23:40 -0300 Subject: signal: Add __libc_sigaction The generic implementation basically handle the system agnostic logic (filtering out the invalid signals) while the __libc_sigaction is the function with implements the system and architecture bits. Checked on x86_64-linux-gnu and i686-linux-gnu. --- sysdeps/unix/sysv/linux/arm/libc_sigaction.c | 39 ++++++++++++++++++++++++++++ sysdeps/unix/sysv/linux/arm/sigaction.c | 39 ---------------------------- 2 files changed, 39 insertions(+), 39 deletions(-) create mode 100644 sysdeps/unix/sysv/linux/arm/libc_sigaction.c delete mode 100644 sysdeps/unix/sysv/linux/arm/sigaction.c (limited to 'sysdeps/unix/sysv/linux/arm') diff --git a/sysdeps/unix/sysv/linux/arm/libc_sigaction.c b/sysdeps/unix/sysv/linux/arm/libc_sigaction.c new file mode 100644 index 0000000..de06131 --- /dev/null +++ b/sysdeps/unix/sysv/linux/arm/libc_sigaction.c @@ -0,0 +1,39 @@ +/* Copyright (C) 1997-2021 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.
