2 ------------------

4 Compared to the previous official snapshot (November 2004) the
5 current version of oscpack includes a re-written set of network
6 classes and some changes to the syntax of the networking code. It no
7 longer uses threads, which means that you don't need to use sleep()
8 if you are writing a simple single-threaded server, or you need to
9 spawn your own threads in a more complex application.
10
11 The list below summarises the changes if you are porting code from
12 the previous release.
13
14 - there are no longer any threads in oscpack. if you need to
15 set up an asynchronous listener you can create your own thread
16 and call Run on an instance of SocketReceiveMultiplexer or
17 UdpListeningReceiveSocket (see ip/UdpSocket.h) yourself.
18
19 - host byte order is now used for network (IP) addresses
20
21 - functions which used to take two parameters <address, port>
22 now take an instance of IpEndpointName (see
23 ip/IpEndpointName.h) this class has a number of convenient
24 constructors for converting numbers and strings to internet
25 addresses. For example there is one which takes a string and
26 another that take the dotted address components as separate
27 parameters.
28
29 - The UdpTransmitPort class, formerly in UdpTransmitPort.h, is
30 now called UdpTransmitSocket, which is simply a convenience
31 class derived from UdpSocket (see ip/UdpSocket.h). Where you
32 used to use the constructor UdpTransmitPort( address, port) now
33 you can use UdpTransmitSocket( IpEndpointName( address, port )
34 ) or you can any of the other possible ctors to IpEndpointName
35 () (see above). The Send() method is unchanged.
36
37 - The packet listener base class is now located in
38 ip/PacketListener.h instead of PacketListenerPort.h. The
39 ProcessPacket method now has an additional parameter indicating
40 the remote endpoint
41
42 - The preferred way to set up listeners is with
43 SocketReceiveMultiplexer (in ip/UdpSocket.h), this also allows
44 attaching periodic timers. For simple applications which only
45 listen to a single socket with no timers you can use
46 UdpListeningReceiveSocket (also in UdpSocket.h) See
47 osc/OscReceiveTest.cpp or osc/OscDump.cpp for examples of this.
48 This is more or less equivalent to the UdpPacketListenerPort
49 object in the old oscpack versions except that you need to
50 explicitly call Run() before it will start receiving packets
51 and it runs in the same thread, not a separate thread so Run()
52 won't usually return.
53
54 - Explicit calls to InitializeNetworking() and
55 TerminateNetworking() are no longer required for simple
56 applications (more complex windows applications should
57 instantiate NetworkInitializer in main() or WinMain (see
58 ip/NetworkingUtils.h/.cpp)
59
60 - The OscPacketListener base class (OscPacketListener.h) was
61 added to make traversing OSC packets easier, it handles bundle
62 traversal automatically so you only need to process messages in
63 your derived classes.
64
65 - On Windows be sure to link with ws2_32.lib or you will see
66 a linker error about WSAEventSelect not being found. Also you
67 will need to link with winmm.lib for timeGetTime()
