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.
