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.

Thanks to Till Bovermann for helping with POSIX networking code and

Mac compatibility, and to Martin Kaltenbrunner and the rest of the

reacTable team for giving me a reason to finish this library. Thanks

to Merlijn Blaauw for reviewing the interfaces. Thanks to Xavier Oliver

for additional help with Linux builds and POSIX implementation details.
