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 separat-
ing the millenia. Next, the field is assumed to be a number: It is
interpreted as hexadecimal if there is a leading ‘0x’ (as in C), a trail-
ing ‘H’ (as in Mesa), or there are any super-decimal digits present. It
is interpreted as octal is there is a leading ‘0’ and there are no super-
octal digits. Otherwise, it is converted as a decimal number.
RETURN VALUES
None. (See BUGS.)

HISTORY
The precursor ns_addr() and ns_ntoa() functions appeared in 4.3BSD.
BUGS
The string returned by ipx_ntoa() resides in a static memory area. The
function ipx_addr() should diagnose improperly formed input, and there
should be an unambiguous way to recognize this.

NAME
iso_addr, iso_ntoa - network address conversion routines for Open System
Interconnection
SYNOPSIS
#include < sys/types.h>
#include < netiso/iso.h>
struct iso_addr *
iso_addr(char *cp);
char *
iso_ntoa(struct iso_addr *isoa);
DESCRIPTION
The routine iso_addr() interprets character strings representing OSI
addresses, returning binary information suitable for use in system calls.
The routine iso_ntoa() takes OSI addresses and returns ASCII strings rep-
resenting NSAPs (network service access points) in a notation inverse to
that accepted by iso_addr().
Unfortunately, no universal standard exists for representing OSI network
addresses.
