This is a bulk mport of Mike's IPX/SPX protocol stacks and all the
related gunf that goes with it..
it is not guaranteed to work 100% correctly at this time
but as we had several people trying to work on it
I figured it would be better to get it checked in so
they could all get teh same thing to work on..

Mikes been using it for a year or so
but on 2.0

more changes and stuff will be merged in from other developers now that this is in.

+.Tn IPX
+address conversion routines
+.Sh SYNOPSIS
+.Fd #include <sys/types.h>
+.Fd #include <netipx/ipx.h>
+.Ft struct ipx_addr 
+.Fn ipx_addr "char *cp"
+.Ft char *
+.Fn ipx_ntoa "struct ipx_addr ipx"
+.Sh DESCRIPTION
+The routine
+.Fn ipx_addr
+interprets character strings representing
+.Tn IPX
+addresses, returning binary information suitable
+for use in system calls.
+The routine
+.Fn ipx_ntoa
+takes
+.Tn IPX
+addresses and returns
+.Tn ASCII
+strings representing the address in a
+notation in common use:
+.Bd -filled -offset indent
+<network number>.<host number>.<port number>
+.Ed
+.Pp
+Trailing zero fields are suppressed, and each number is printed in hexadecimal,
+in a format suitable for input to 
+.Fn ipx_addr .
+Any fields lacking super-decimal digits will have a
+trailing
+.Ql H
+appended.
+.Pp
+An effort has been made to insure that
+.Fn ipx_addr
+be compatible with most formats in common use.
+It will first separate an address into 1 to 3 fields using a single delimiter
+chosen from
+period
+.Ql \&. ,
+colon
+.Ql \&:
+or pound-sign
+.Ql \&# .
+Each field is then examined for byte separators (colon or period).
+If there are byte separators, each subfield separated is taken to be
+a small hexadecimal number, and the entirety is taken as a network-byte-ordered
+quantity to be zero extended in the high-network-order bytes.
+Next, the field is inspected for hyphens, in which case
+the field is assumed to be a number in decimal notation
+with hyphens separating the millenia.
+Next, the field is assumed to be a number:
+It is interpreted
+as hexadecimal if there is a leading
+.Ql 0x
+(as in C),
+a trailing
+.Ql H
+(as in Mesa), or there are any super-decimal digits present.
+It is interpreted as octal is there is a leading
+.Ql 0
+and there are no super-octal digits.
+Otherwise, it is converted as a decimal number.
+.Sh RETURN VALUES
+None. (See
+.Sx BUGS . )
+.Sh SEE ALSO
+.Xr hosts 5 ,
+.Xr networks 5 ,
+.Xr ns 5 ,
+.Sh HISTORY
+The precursor
+.Fn ns_addr
+and
+.Fn ns_toa
+functions appeared in 
+.Bx 4.3 .
+.Sh BUGS
+The string returned by
+.Fn ipx_ntoa
+resides in a static memory area.
+The function
+.Fn ipx_addr
+should diagnose improperly formed input, and there should be an unambiguous
+way to recognize this.
