   2 ------------------
   3
   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()
