	Change History (most recent first):

		<13>	 7/30/91	JL		Updated Copyright.
		<12>	  2/5/91	stb		ngk: remove registerOnNetwork
		<11>	 1/28/91	LN		Checked in Database generate file from DSG. Grouping enums into
									groups of 20 for C++ support.
		<10>	12/14/90	JWM		do some beautification of the header file
		 <9>	12/13/90	JWM		New error code for PostHighLevelEvent which is returned if we
									are establishing a remote connection and the application is not
									frontmost or is being coerced.
		 <8>	 11/7/90	JL		Changed all #defines to anonymous enums. Made this more C++
									compatible.
		 <7>	 9/27/90	ngk		In GetSpecificHighLevelEvent changed "unsigned long *params" to
									"void *yourDataPtr"
		 <6>	 9/15/90	ngk		updated to work with new PPCToolBox.h PortName -> PPCPortRec,
									PortNamePtr -> PPCPortPtr, LocName -> LocationNameRec
		 <5>	 4/10/90	JWM		add interface for GetPortNameFromProcessSerialNumber and remove
									two postingOptions which will not be implemented.

	To Do:		remove eppc resource type definition
