From 319b9ad4bccedb2a6b1a222cf446e873b2bc6de1 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Mon, 11 Jul 2011 14:50:24 -0400 Subject: Generalize framework to register monitoring of files in nscd nscd can clear caches when certain files change. The list of files was hardcoded so far and worked for nss_files and nss_dns and those modules which need no monitoring. nss_db, for instance, has its own set of files to monitor. Now the NSS modules themselves can request that certain files are monitored. --- nss/nss_db/db-init.c | 54 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 54 insertions(+) create mode 100644 nss/nss_db/db-init.c (limited to 'nss/nss_db/db-init.c') diff --git a/nss/nss_db/db-init.c b/nss/nss_db/db-init.c new file mode 100644 index 0000000000..8228d61f57 --- /dev/null +++ b/nss/nss_db/db-init.c @@ -0,0 +1,54 @@ +/* Initialization in nss_db module. + Copyright (C) 2011 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.
