NAME

       fmt_ip6c - write a formatted ASCII representation of an IPv6 number

SYNTAX

       #include <ip6.h>

       unsigned int fmt_ip6c(char *dest,const char ip[16]);

DESCRIPTION

       fmt_ip6c  formats  an  IPv6  number  in  ASCII representation from ip and writes the result into dest. It
       returns the number of bytes written.

       fmt_ip6c will apply "::" compression to the output.

       If ip is an IPv4-mapped IPv6 address, fmt_ip6c will output it as IPv4 address.

       If dest equals FMT_LEN (i.e. is zero), fmt_ip6c returns the number of bytes it would have written.

       fmt_ip6c does not append \0.

       For convenience, ip6.h defines the integer IP6_FMT to be big enough to contain  every  possible  fmt_ip6c
       output plus \0.

EXAMPLE

       #include <ip6.h>

         char buf[IP6_FMT];
         char ip[16];
         buf[fmt_ip6c(buf,ip)]=0;
