NAME

       fmt_ip6ifc - write a formatted ASCII representation of an IPv6 number

SYNTAX

       #include <libowfat/ip6.h>

       unsigned int fmt_ip6ifc(char *dest,const char ip[16],uint32 scope_id);

DESCRIPTION

       fmt_ip6ifc  formats  an  IPv6  number in ASCII representation from ip and writes the result into dest. It
       returns the number of bytes written.

       fmt_ip6ifc will apply "::" compression to the output.

       If ip is an IPv4-mapped IPv6 address, fmt_ip6ifc will output it as IPv4 address.

       If dest equals FMT_LEN (i.e. is zero), fmt_ip6ifc 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_ip6ifc 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_ip6ifc(buf,ip,sid)]=0;
