From b8ec7553efd0108cf453e763af5ba19f537366b2 Mon Sep 17 00:00:00 2001 From: Aki Niemi Date: Tue, 18 May 2010 17:07:54 +0300 Subject: [PATCH] Add network time support Adding a new notify function in the netreg atom for notifying a received Network Identification and Timezone (NITZ) indication. This data is consumed via a nettime plugin, of which there is also an example. --- Makefile.am | 10 ++-- include/netreg.h | 2 + include/nettime.h | 52 ++++++++++++++++ include/types.h | 11 ++++ plugins/example_nettime.c | 84 ++++++++++++++++++++++++++ src/modem.c | 1 + src/nettime.c | 121 ++++++++++++++++++++++++++++++++++++++ src/network.c | 11 ++++ src/ofono.h | 8 +++ 9 files changed, 296 insertions(+), 4 deletions(-) create mode 100644 include/nettime.h create mode 100644 plugins/example_nettime.c create mode 100644 src/nettime.c diff --git a/Makefile.am b/Makefile.am index 7fd862f1..ed13346b 100644 --- a/Makefile.am +++ b/Makefile.am @@ -12,7 +12,8 @@ include_HEADERS = include/log.h include/plugin.h include/history.h \ include/netreg.h include/voicecall.h include/devinfo.h \ include/cbs.h include/call-volume.h \ include/gprs.h include/gprs-context.h \ - include/radio-settings.h include/stk.h + include/radio-settings.h include/stk.h \ + include/nettime.h nodist_include_HEADERS = include/version.h @@ -242,8 +243,8 @@ builtin_sources += plugins/ste.c endif if MAINTAINER_MODE -builtin_modules += example_history -builtin_sources += plugins/example_history.c +builtin_modules += example_history example_nettime +builtin_sources += plugins/example_history.c plugins/example_nettime.c endif sbin_PROGRAMS = src/ofonod @@ -260,7 +261,8 @@ src_ofonod_SOURCES = $(gdbus_sources) $(builtin_sources) \ src/simutil.h src/simutil.c src/storage.h \ src/storage.c src/cbs.c src/watch.c src/call-volume.c \ src/gprs.c src/idmap.h src/idmap.c \ - src/radio-settings.c src/stkutil.h src/stkutil.c + src/radio-settings.c src/stkutil.h src/stkutil.c \ + src/nettime.c src_ofonod_LDADD = $(builtin_libadd) @GLIB_LIBS@ @DBUS_LIBS@ @CAPNG_LIBS@ -ldl diff --git a/include/netreg.h b/include/netreg.h index 00794776..88609604 100644 --- a/include/netreg.h +++ b/include/netreg.h @@ -93,6 +93,8 @@ struct ofono_netreg_driver { void ofono_netreg_strength_notify(struct ofono_netreg *netreg, int strength); void ofono_netreg_status_notify(struct ofono_netreg *netreg, int status, int lac, int ci, int tech); +void ofono_netreg_time_notify(struct ofono_netreg *netreg, + struct ofono_network_time *info); int ofono_netreg_driver_register(const struct ofono_netreg_driver *d); void ofono_netreg_driver_unregister(const struct ofono_netreg_driver *d); diff --git a/include/nettime.h b/include/nettime.h new file mode 100644 index 00000000..0f23cc70 --- /dev/null +++ b/include/nettime.h @@ -0,0 +1,52 @@ +/* + * + * oFono - Open Telephony stack for Linux + * + * Copyright (C) 2010 Nokia Corporation and/or its subsidiary(-ies). + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + * + * This program 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.
