NAME
       scan_ip6 - parse an IPv6 number and interface in ASCII representation

SYNTAX
       #include <ip6.h>

       int scan_ip6if(const char *src,char ip[16],uint32* scope_id);

DESCRIPTION
       scan_ip6if  parses an IPv6 number in RFC1884 ASCII representation from src and writes the result into ip. If the IPv6 number is followed by
       the percent sign, scan_ip6if takes the word following that, tries to parse it as network interface and writes the result to scope_id.

       It returns the number of bytes read from src or 0 if the parsing failed.

       scan_ip6if  accepts  upper  and	lower  case  hex  letters,  it	understands  "::"  compression	and   partial	IPv4   addresses   as	in
       "::FFFF:129.144.52.38".

       To  allow  transparent  usage  of IPv4 in IPv6 applications, scan_ip6if also understands IPv4 addresses in dotted-decimal notation and will
       return an IPv4-mapped IPv6 address (i.e. "127.0.0.1" will be parsed as "::FFFF:127.0.0.1".

       Unlike many other IP parsing routines, scan_ip6if does not recognize octal (like 0177.0.0.1) or hexadecimal numbers  (like  0x7f000001)	in
       the IPv4 part.

EXAMPLE
       #include <str.h>
       #include <ip6.h>

	 char buf[]="::1%lo";
	 char ip[16];
	 uint32 scope_id;
	 if (scan_ip6if(buf,ip,&scope_id) != str_len(buf))
	   parse_error();
