#oscpack -- Open Sound Control packet manipulation library A simple C++ library for packing and unpacking OSC packets. http://www.rossbencina.com/code/oscpack

Copyright (c) 2004-2013 Ross Bencina rossb@audiomulch.com

Oscpack is simply a set of C++ classes for packing and unpacking OSC packets. Oscpack includes a minimal set of UDP networking classes for Windows and POSIX. The networking classes are sufficient for writing many OSC applications and servers, but you are encouraged to use another networking framework if it better suits your needs. Oscpack is not an OSC application framework. It doesn't include infrastructure for constructing or routing OSC namespaces, just classes for easily constructing, sending, receiving and parsing OSC packets. The library should also be easy to use for other transport methods (e.g. serial).

The key goals of the oscpack library are:

- Be a simple and complete implementation of OSC
- Be portable to a wide variety of platforms
- Allow easy development of robust OSC applications 
  (for example it should be impossible to crash a server 
  by sending it malformed packets, and difficult to create 
  malformed packets.)

Here's a quick run down of the key files:

osc/OscReceivedElements -- classes for parsing a packet osc/OscPrintRecievedElements -- iostream << operators for printing packet elements osc/OscOutboundPacketStream -- a class for packing messages into a packet osc/OscPacketListener -- base class for listening to OSC packets on a UdpSocket ip/IpEndpointName -- class that represents an IP address and port number ip/UdpSocket -- classes for UDP transmission and listening sockets tests/OscUnitTests -- unit test program for the OSC modules tests/OscSendTests -- examples of how to send messages tests/OscReceiveTest -- example of how to receive the messages sent by OSCSendTests examples/OscDump -- a program that prints received OSC packets examples/SimpleSend -- a minimal program to send an OSC message examples/SimpleReceive -- a minimal program to receive an OSC message

osc/ contains all of the OSC related classes ip/ contains the networking classes

ip/windows contains the Windows implementation of the networking classes ip/posix contains the POSIX implementation of the networking classes

Building

The idea is that you will embed this source code in your projects as you see fit. The Makefile has an install rule for building a shared library and installing headers in usr/local. It can also build a static library. There is a CMakeLists.txt for building with cmake.

Makefile builds ...............

The Makefile works for Linux and Max OS X. It should also work on other platforms that have make. Just run:

$ make

You can run "make install" if you like.

Cmake builds ............

There is a CMakeLists.txt file which has been tested with cmake on Windows and Linux. It should work on other platforms too. For example, to generate a Visual Studio 10 project, run cmake like this:

cmake -G "Visual Studio 10"

Run cmake without any parameters to get a list of available generators.

Mingw build batch file ......................

For Windows there is a batch file for doing a simple test build with MinGW gcc called make.MinGW32.bat. This will build the test executables and oscdump in ./bin and run the unit tests.

Note:

In some rare instances you may need to edit the Makefile or osc/OscHostEndianness.h to configure oscpack for the endianness of your processor (see the comments at the top of the Makefile for details).

Verification test

To run the unit tests:

$ ./bin/OscUnitTests

To run the send and receive tests. Open two terminals. In one run:

$ ./bin/OscReceiveTest

Then in the other terminal run:

$./bin/OscSendTests

You should see an indication that the messages were received in the first terminal.

Note that OscSendTests intentionally sends some unexpected message parameters to test exception handling in the receiver. You will see some "error while parsing message" messages printed.

You can use ./bin/OscDump to print out OSC messages received from any program, including the test programs.
