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.

.Sh NAME

.\" .Nd Novell
.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.
