Expand description

\brief This function parses a CN string as an IP address.

\param cn The CN string to parse. CN string MUST be null-terminated. \param dst The target buffer to populate with the binary IP address. The buffer MUST be 16 bytes to save IPv6, and should be 4-byte aligned if the result will be used as struct in_addr. e.g. uint32_t dst[4]

\note \p cn is parsed as an IPv6 address if string contains ‘:’, else \p cn is parsed as an IPv4 address.

\return Length of binary IP address; num bytes written to target. \return \c 0 on failure to parse CN string as an IP address.
