-.Dt ISO_ADDR 3
-.Os
-.Sh NAME
-.Nm iso_addr ,
-.Nm iso_ntoa
-.Nd "elementary network address conversion routines for Open System Interconnection
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In sys/types.h
-.In netiso/iso.h
-.Ft struct iso_addr *
-.Fn iso_addr "char *cp"
-.Ft char *
-.Fn iso_ntoa "struct iso_addr *isoa"
-.Sh DESCRIPTION
-The routine
-.Fn iso_addr
-interprets character strings representing
-.Tn OSI
-addresses, returning binary information suitable
-for use in system calls.
-The routine
-.Fn iso_ntoa
-takes
-.Tn OSI
-addresses and returns
-.Tn ASCII
-strings representing NSAPs (network service
-access points) in a
-notation inverse to that accepted by
-.Fn iso_addr .
-.Pp
-Unfortunately, no universal standard exists for representing
-.Tn OSI
-network addresses.
-.Pp
-The format employed by
-.Fn iso_addr
-is a sequence of hexadecimal
-.Dq digits
-(optionally separated by periods),
-of the form:
-.Bd -ragged -offset indent
-<hex digits>.<hex digits>.<hex digits>
-.Ed
-.Pp
-Each pair of hexadecimal digits represents a byte
-with the leading digit indicating the higher-ordered bits.
-A period following an even number of bytes has no
-effect (but may be used to increase legibility).
-A period following an odd number of bytes has the
-effect of causing the byte of address being translated
-to have its higher order bits filled with zeros.
-.Sh RETURN VALUES
-The
-.Fn iso_ntoa
-function
-always returns a null terminated string.
-The
-.Fn iso_addr
-function
-always returns a pointer to a struct iso_addr.
-(See
-.Sx BUGS . )
-.Sh SEE ALSO
-.Xr iso 4
-.Sh HISTORY
-The
-.Fn iso_addr
-and
-.Fn iso_ntoa
-functions appeared in
-.Bx 4.3 Reno .
-.Sh BUGS
-The returned values
-reside in a static memory area.
-.Pp
-The function
-.Fn iso_addr
-should diagnose improperly formed input, and there should be an unambiguous
-way to recognize this.

-.Sh DESCRIPTION
-The routine
-.Fn ns_addr
-interprets character strings representing

-addresses, returning binary information suitable
-for use in system calls.
-The routine
-.Fn ns_ntoa
-takes
-.Tn XNS

-.Tn ASCII
-strings representing the address in a
-notation in common use in the Xerox Development Environment:
-.Bd -ragged -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 ns_addr .
-Any fields lacking super-decimal digits will have a
-trailing
-.Ql H
-appended.
-.Pp
-Unfortunately, no universal standard exists for representing
-.Tn XNS
-addresses.
-An effort has been made to insure that
-.Fn ns_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.
