IPX(3)                    OpenBSD Programmer's Manual                   IPX(3)

     ipx_addr, ipx_ntoa - IPX address conversion routines

     #include <sys/types.h>
     #include <netipx/ipx.h>

     struct ipx_addr
     ipx_addr(char *cp);

     char *
     ipx_ntoa(struct ipx_addr ipx);

     The routine ipx_addr() interprets character strings representing IPX ad-
     dresses, 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 insure 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-or-
     der 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 in-
     terpreted as hexadecimal if there is a leading `0x' (as in C), a trailing
     `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-oc-
     tal digits.  Otherwise, it is converted as a decimal number.

     None. (See BUGS.)

     ns(4),  hosts(5),  networks(5)

     The precursor ns_addr() and ns_ntoa() functions appeared in 4.3BSD.

     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.
