/**

 * in6_pton - convert an IPv6 address from literal to binary representation

 * @src: the start of the IPv6 address string

 * @srclen: the length of the string, -1 means strlen(src)

 * @dst: the binary (u8[16] array) representation of the IPv6 address

 * @delim: the delimiter of the IPv6 address in @src, -1 means no delimiter

 * @end: A pointer to the end of the parsed string will be placed here

 *

 * Return one on success, return zero when any error occurs

 * and @end will point to the end of the parsed string.
