 enum BIO_hostserv_priorities {
     BIO_PARSE_PRIO_HOST, BIO_PARSE_PRIO_SERV
 };
 int BIO_parse_hostserv(const char *hostserv, char **host, char **service,
                        enum BIO_hostserv_priorities hostserv_prio);
The syntax the BIO_parse_hostserv() recognises is:
 host + ':' + service
 host + ':' + '*'
 host + ':'
        ':' + service
 '*'  + ':' + service
 host
 service
The host part can be a name or an IP address. If it's a IPv6 address, it MUST be enclosed in brackets, such as '[::1]'.
The service part can be a service name or its port number. A service name will be mapped to a port number using the system function getservbyname().
The returned values will depend on the given hostserv string and hostserv_prio, as follows:
 host + ':' + service  => *host = "host", *service = "service"
 host + ':' + '*'      => *host = "host", *service = NULL
 host + ':'            => *host = "host", *service = NULL
        ':' + service  => *host = NULL, *service = "service"
  '*' + ':' + service  => *host = NULL, *service = "service"
 in case no ':' is present in the string, the result depends on
 hostserv_prio, as follows:
 when hostserv_prio == BIO_PARSE_PRIO_HOST
 host                 => *host = "host", *service untouched
 when hostserv_prio == BIO_PARSE_PRIO_SERV
 service              => *host untouched, *service = "service"
