The routine ipx_ntoa() takes IPX addresses and returns ASCII strings rep-     resenting the address in a notation in common use:           &lt;network number&#62;.&lt;host number&#62;.&lt;port number&#62;     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.

The     function ipx_addr() should diagnose improperly formed input, and there     should be an unambiguous way to recognize this.BSD                              June 4, 1993                              BSD    </PRE></TD></TR></TABLE></DIV><DIVCLASS="NAVFOOTER"><HRALIGN="LEFT"WIDTH="100%"><TABLESUMMARY="Footer navigation table"WIDTH="100%"BORDER="0"CELLPADDING="0"CELLSPACING="0"><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top"><AHREF="net-common-tcpip-manpages-inet-net.html"ACCESSKEY="P">Prev</A></TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><AHREF="ecos-ref.html"ACCESSKEY="H">Home</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top"><AHREF="net-common-tcpip-manpages-iso-addr.html"ACCESSKEY="N">Next</A></TD></TR><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top">inet_net</TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><AHREF="tcpip-library-reference.html"ACCESSKEY="U">Up</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top">iso_addr</TD></TR></TABLE></DIV></BODY></HTML>
