fmt_ip6if(3)		    Library Functions Manual		    fmt_ip6if(3)

NAME
     fmt_ip6if - write a formatted ASCII representation of an IPv6 number

SYNTAX
     #include <libowfat/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 possi-
     ble 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 <libowfat/ip6.h>

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