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