From 08f600749ecfeedfcd70c4dd8d0a9fa6c4380a1c Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sun, 14 Apr 2002 20:15:40 +0000 Subject: Update. * include/sys/socket.h: Declare __libc_sa_len_internal and define SA_LEN macro to use it if not NOT_IN_libc. * sysdeps/unix/sysv/linux/sa_len.c: Use INTDEF for __libc_sa_len. * include/fcntl.h: Declare __open_internal and define __open and __libc_open macros if not NOT_IN_libc. * sysdeps/generic/open.c: Use INTDEF for __open. * sysdeps/mach/hurd/open.c: Likewise. * sysdeps/unix/sysv/aix/open.c: Likewise. * sysdeps/unix/syscalls.list: Add __open_internal alias. * sysdeps/generic/check_fds.c: Make sure newly opened file descriptor has correct number. * include/fcntl.h: Define __libc_fcntl macro if not NOT_IN_libc. * sysdeps/mach/hurd/fcntl.c: Undefine __libc_fcntl as well. * sysdeps/unix/sysv/aix/fcntl.c: Likewise. * sysdeps/unix/sysv/linux/i386/fcntl.c: Likewise. * include/wctype.h: Declare __iswalpha_l_internal, __iswdigit_l_internal, __iswspace_l_internal, __iswxdigit_l_internal, and __iswctype_internal. Define __iswalpha_l, __iswctype, __iswdigit_l, __iswspace_l, and __iswxdigit_l macros if not NOT_IN_libc. * wctype/iswctype.c: Use INTDEF for __iswctype. * wctype/wcfuncs_l.c: Use INTDEF for all __iswXXX_l. --- sysdeps/generic/check_fds.c | 14 +++++++++----- sysdeps/generic/open.c | 5 ++++- sysdeps/mach/hurd/fcntl.c | 1 + sysdeps/mach/hurd/open.c | 6 +++++- sysdeps/unix/syscalls.list | 2 +- sysdeps/unix/sysv/aix/fcntl.c | 1 + sysdeps/unix/sysv/aix/open.c | 6 +++++- sysdeps/unix/sysv/linux/i386/fcntl.c | 1 + sysdeps/unix/sysv/linux/sa_len.c | 3 ++- 9 files changed, 29 insertions(+), 10 deletions(-) (limited to 'sysdeps') diff --git a/sysdeps/generic/check_fds.c b/sysdeps/generic/check_fds.c index 083b72de16..ff9562de08 100644 --- a/sysdeps/generic/check_fds.c +++ b/sysdeps/generic/check_fds.c @@ -1,4 +1,4 @@ -/* Copyright (C) 2000 Free Software Foundation, Inc. +/* Copyright (C) 2000, 2002 Free Software Foundation, Inc.
