fmt_ip6ifc(3)		    Library Functions Manual		   fmt_ip6ifc(3)

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 ad-
     dress.

     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 possi-
     ble 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;
