;Developer Notes:
; 0. This MacTCP header replaces what used to be defined in the following header files
; MacTCPCommonTypes.h
; GetMyIPAddr.h
; MiscIPPB.h
; TCPPB.h
; UDPPB.h
;
; When the various control calls are made to the ip driver, you must set up a
; NewRoutineDescriptor for every non-nil completion routine and/or notifyProc parameter.
; Otherwise, the 68K driver code, will not correctly call your routine.
; 1. For ipctlGetAddr Control calls, use NewGetIPIOCompletionProc
; to set up a GetIPIOCompletionUPP universal procptr to pass as
; the ioCompletion parameter.
; 2. For the ipctlEchoICMP and ipctlLAPStats Control calls, use
; NewIPIOCompletion to set up a IPIOCompletionUPP universal procptr
; to pass in the ioCompletion field of the parameter block.
; 3. For TCPCreatePB Control calls, use NewTCPNotifyProc to set up a
; TCPNotifyUPP universal procptr to pass in the notifyProc field
; of the parameter block
; 4. For all of the TCP Control calls using the TCPiopb parameter block,
; use NewTCPIOCompletionProc to set up a TCPIOCompletionUPP
; universal procptr to pass in the ioCompletion field of the paramter
; block.
; 5. For UDBCreatePB Control calls, use NewUDPNotifyProc to set up a
; UDPNotifyUPP universal procptr to pass in the notifyProc field
; of the parameter block
; 6. For all of the UDP Control calls using the UDPiopb parameter block,
; use NewUDPIOCompletionProc to set up a UDPIOCompletionUPP
; universal procptr to pass in the ioCompletion field of the paramter
; block.
; 7. For all calls implementing a notifyProc or ioCompletion routine
; which was set up using a NewTCPRoutineProc call, do not call
; DisposeRoutineSDescriptor on the universal procptr until
; after the completion or notify proc has completed.
