From 4bec2216312c231b2082f0b462328b1270b00836 Mon Sep 17 00:00:00 2001 From: "Bradley T. Hughes" Date: Tue, 27 Jul 2010 09:46:09 +0200 Subject: Add multicastsender and multicastreceiver examples These are clones of the broadcastsender and broadcastreceiver examples, modified to use the multicast API. I've made sure that the examples are linked in the appropriate places as well. --- examples/network/multicastreceiver/main.cpp | 51 +++++++++++++ .../multicastreceiver/multicastreceiver.pro | 12 +++ examples/network/multicastreceiver/receiver.cpp | 84 ++++++++++++++++++++ examples/network/multicastreceiver/receiver.h | 70 +++++++++++++++++ examples/network/multicastsender/main.cpp | 51 +++++++++++++ .../network/multicastsender/multicastsender.pro | 12 +++ examples/network/multicastsender/sender.cpp | 89 ++++++++++++++++++++++ examples/network/multicastsender/sender.h | 77 +++++++++++++++++++ examples/network/network.pro | 4 +- 9 files changed, 449 insertions(+), 1 deletion(-) create mode 100644 examples/network/multicastreceiver/main.cpp create mode 100644 examples/network/multicastreceiver/multicastreceiver.pro create mode 100644 examples/network/multicastreceiver/receiver.cpp create mode 100644 examples/network/multicastreceiver/receiver.h create mode 100644 examples/network/multicastsender/main.cpp create mode 100644 examples/network/multicastsender/multicastsender.pro create mode 100644 examples/network/multicastsender/sender.cpp create mode 100644 examples/network/multicastsender/sender.h (limited to 'examples/network') diff --git a/examples/network/multicastreceiver/main.cpp b/examples/network/multicastreceiver/main.cpp new file mode 100644 index 0000000000..8483271ad2 --- /dev/null +++ b/examples/network/multicastreceiver/main.cpp @@ -0,0 +1,51 @@ +/**************************************************************************** +** +** Copyright (C) 2010 Nokia Corporation and/or its subsidiary(-ies). +** All rights reserved. +** Contact: Nokia Corporation (qt-info@nokia.com) +** +** This file is part of the examples of the Qt Toolkit. +** +** $QT_BEGIN_LICENSE:BSD$ +** You may use this file under the terms of the BSD license as follows: +** +** "Redistribution and use in source and binary forms, with or without +** modification, are permitted provided that the following conditions are +** met: +** * Redistributions of source code must retain the above copyright +** notice, this list of conditions and the following disclaimer. +** * Redistributions in binary form must reproduce the above copyright +** notice, this list of conditions and the following disclaimer in +** the documentation and/or other materials provided with the +** distribution. +** * Neither the name of Nokia Corporation and its Subsidiary(-ies) nor +** the names of its contributors may be used to endorse or promote +** products derived from this software without specific prior written +** permission. +** +** THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +** "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +** LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +** A PARTICULAR PURPOSE ARE DISCLAIMED.
