NAME

       fmt_ip6if - write a formatted ASCII representation of an IPv6 number

SYNTAX

       #include <ip6.h>

       unsigned int fmt_ip6if(char *dest,const char ip[16],uint32 scope_id);

DESCRIPTION

       fmt_ip6if  formats  an  IPv6  number in ASCII representation from ip and writes the result
       into dest. It returns the number of bytes written.

       fmt_ip6if will apply "::" compression to the output.

       If ip is an IPv4-mapped IPv6 address, fmt_ip6if will output  the  last  4  bytes  as  IPv4
       number in dotted-decimal notation.

       If dest equals FMT_LEN (i.e. is zero), fmt_ip6if returns the number of bytes it would have
       written.

       fmt_ip6 does not append \0.

       ip6.h defines the integer IP6_FMT to be big  enough  to  contain  every  possible  fmt_ip6
       output plus \0.  However, for fmt_ip6if you need to add 1 for the '%' and IF_NAMESIZE from
       <net/if.h> for the interface name.

EXAMPLE

       #include <ip6.h>

         char buf[IP6_FMT];
         char ip[16];
         scope_id sid;
         buf[fmt_ip6if(buf,ip,sid)]=0;
