From 1773d1ba5fa4c82e3a609f11742e159039b01c24 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Wed, 26 May 2004 06:42:16 +0000 Subject: Update. 2004-05-25 Ulrich Drepper * nss/digits_dots.c (__nss_hostname_digits_dots): Remove typep and flags parameter, convert afp to simple int parameter. Adjust code. typep was never != NULL and flags therefore also unused. *afp is never modified. * nss/nsswitch.h: Adjust __nss_hostname_digits_dots prototype. * nss/getXXbyYY.c: Remove HAVE_TYPE handling. Adjust af parameter handling for __nss_hostname_digits_dots calls. * nss/getXXbyYY_r.c: Likewise. * elf/dl-load.c (_dl_map_object_from_fd): Map DSOs with MAP_DENYWRITE. --- nss/digits_dots.c | 84 +++++++++++++++---------------------------------------- nss/getXXbyYY.c | 15 +++------- nss/getXXbyYY_r.c | 12 ++------ nss/nsswitch.h | 6 ++-- 4 files changed, 32 insertions(+), 85 deletions(-) (limited to 'nss') diff --git a/nss/digits_dots.c b/nss/digits_dots.c index 4dc897c32c..17207945b9 100644 --- a/nss/digits_dots.c +++ b/nss/digits_dots.c @@ -1,4 +1,4 @@ -/* Copyright (C) 1997, 1999, 2000, 2001 Free Software Foundation, Inc. +/* Copyright (C) 1997, 1999, 2000, 2001, 2004 Free Software Foundation, Inc.
