NAME
ipx_addr, ipx_ntoa - IPX address conversion routines
SYNOPSIS
#include <sys/types.h>
#include <netipx/ipx.h>
struct ipx_addr
ipx_addr(const char *cp);
char *
ipx_ntoa(struct ipx_addr ipx);
DESCRIPTION
The routine ipx_addr() interprets character strings representing IPX
addresses, returning binary information suitable for use in system calls.
The routine ipx_ntoa() takes IPX addresses and returns ASCII strings rep-
resenting the address in a notation in common use:
<network number>.<host number>.<port number>
Trailing zero fields are suppressed, and each number is printed in hex-
adecimal, in a format suitable for input to ipx_addr(). Any fields lack-
ing super-decimal digits will have a trailing `H' appended.
An effort has been made to ensure that 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 (`.'), colon (`:'), or
pound-sign (`#'). 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 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.)
SEE ALSO
ns(4), hosts(5), networks(5)
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.
