scan_ip6(3) Library Functions Manual scan_ip6(3) NAME scan_ip6 - parse an IPv6 number in ASCII representation SYNTAX #include <libowfat/ip6.h> int scan_ip6(const char *src,char ip[16]); DESCRIPTION scan_ip6 parses an IPv6 number in RFC1884 ASCII representation from src and writes the result into ip. It returns the number of bytes read from src or 0 if the parsing failed. scan_ip6 accepts upper and lower case hex letters, it understands "::" com- pression and partial IPv4 addresses as in "::FFFF:129.144.52.38". To allow transparent usage of IPv4 in IPv6 applications, scan_ip6 also un- derstands 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_ip6 does not recognize octal (like 0177.0.0.1) or hexadecimal numbers (like 0x7f000001) in the IPv4 part. EXAMPLE #include <libowfat/str.h> #include <libowfat/ip6.h> char buf[]="::1"; char ip[16]; if (scan_ip6(buf,ip) != str_len(buf)) parse_error(); SEE ALSO scan_ip6if(3), fmt_ip6(3), scan_ip4(3), inet_pton(3) scan_ip6(3)
