NAME

       fmt_ip6 - write a formatted ASCII representation of an IPv6 number

SYNTAX

       #include <libowfat/ip6.h>

       unsigned int fmt_ip6(char *dest,const char ip[16]);

DESCRIPTION

       fmt_ip6  formats  an  IPv6  number  in  ASCII  representation from ip and writes the result into dest. It
       returns the number of bytes written.

       fmt_ip6 will apply "::" compression to the output.

       If ip is an IPv4-mapped IPv6 address, fmt_ip6 will output the last 4 bytes  as  IPv4  number  in  dotted-
       decimal notation.

       If dest equals FMT_LEN (i.e. is zero), fmt_ip6 returns the number of bytes it would have written.

       fmt_ip6 does not append \0.

       For  convenience,  ip6.h  defines  the integer IP6_FMT to be big enough to contain every possible fmt_ip6
       output plus \0.

EXAMPLE

       #include <libowfat/ip6.h>

         char buf[IP6_FMT];
         char ip[16];
         buf[fmt_ip6(buf,ip)]=0;
