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
       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	<libowfat/ip6.h>

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