  50. Developer Notes:
  51.         0. This MacTCP header replaces what used to be defined in the following header files
  52.             MacTCPCommonTypes.h
  53.             GetMyIPAddr.h
  54.             MiscIPPB.h
  55.             TCPPB.h
  56.             UDPPB.h 
  57.             
  58.             When the various control calls are made to the ip driver, you must set up a 
  59.             NewRoutineDescriptor for every non-nil completion routine and/or notifyProc parameter.  
  60.             Otherwise, the 68K driver code, will not correctly call your routine.
  61.         1. For ipctlGetAddr Control calls, use NewGetIPIOCompletionProc
  62.             to set up a GetIPIOCompletionUPP universal procptr to pass as
  63.             the ioCompletion parameter.
  64.         2. For the ipctlEchoICMP and ipctlLAPStats Control calls, use 
  65.             NewIPIOCompletion to set up a IPIOCompletionUPP universal procptr
  66.             to pass in the ioCompletion field of the parameter block.
  67.         3. For TCPCreatePB Control calls, use NewTCPNotifyProc to set up a
  68.             TCPNotifyUPP universal procptr to pass in the notifyProc field
  69.             of the parameter block
  70.         4. For all of the TCP Control calls using the TCPiopb parameter block,
  71.             use NewTCPIOCompletionProc to set up a TCPIOCompletionUPP
  72.             universal procptr to pass in the ioCompletion field of the paramter
  73.             block.
  74.         5. For UDBCreatePB Control calls, use NewUDPNotifyProc to set up a
  75.             UDPNotifyUPP universal procptr to pass in the notifyProc field
  76.             of the parameter block
  77.         6. For all of the UDP Control calls using the UDPiopb parameter block,
  78.             use NewUDPIOCompletionProc to set up a UDPIOCompletionUPP
  79.             universal procptr to pass in the ioCompletion field of the paramter
  80.             block.
  81.         7. For all calls implementing a notifyProc or ioCompletion routine
  82.             which was set up using a NewTCPRoutineProc call, do not call
  83.             DisposeRoutineSDescriptor on the universal procptr until
  84.             after the completion or notify proc has completed.
