For a nabble is hard to understand using d-bus, there is many libraries and few documentation. I am trying to use lowlevel API ( http://dbus.freedesktop.org/doc/dbus/libdbus-tutorial.html Lowlevel API ). I wrote the code under but don't work. When arrive at "dbus_pending_call_block(pending)" application block to infinity loop. Any suggestion will be appreciated // connect to the bus dbus_bus_get(DBUS_BUS_SESSION, &err); ... // request a name on the bus ret = dbus_bus_request_name(conn, "org.freesmartphone.opimd", DBUS_NAME_FLAG_REPLACE_EXISTING , &err); .... char* stat; DBusMessage* msg; DBusMessageIter iter,array,dict; DBusPendingCall* pending; msg = dbus_message_new_method_call("org.freesmartphone.opimd", // target for the method call "/org/freesmartphone/PIM/Contacts", // object to call on "org.freesmartphone.PIM.Contacts", // interface to call on "Query"); // append arguments dbus_message_iter_init_append(msg, &iter); dbus_message_iter_open_container(&iter, DBUS_TYPE_ARRAY, "{sv}", &array) dbus_message_iter_open_container(&array, DBUS_TYPE_DICT_ENTRY, 0, &dict) dbus_message_iter_close_container(&iter, &array); // send message and get a handle for a reply if (!dbus_connection_send_with_reply (conn, msg, &pending, -1)) { // -1 is de fprintf(stderr, "Out Of Memory!\n"); exit(1); dbus_connection_flush(conn); // free message dbus_message_unref(msg); // block until we receive a reply dbus_pending_call_block(pending); // get the reply message msg = dbus_pending_call_steal_reply(pending); if (NULL == msg) { fprintf(stderr, "Reply Null\n"); exit(1); } // free the pending message handle dbus_pending_call_unref(pending); // read the parameters if (!dbus_message_iter_init(msg, &iter)) fprintf(stderr, "Message has no arguments!\n"); else if (DBUS_TYPE_STRING != dbus_message_iter_get_arg_type(&iter)) fprintf(stderr, "Argument is not string\n"); else dbus_message_iter_get_basic(&iter, &stat); printf("----->Got Reply: %s -- \n",stat ); // free reply and close connection dbus_message_unref(msg);
