Those will need to be freed after +they are used. B<hostserv_prio> helps determine if B<hostserv> shall +be interpreted primarily as a host name or a service name in ambiguous +cases. + +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. + +The returned values will depend on the given B<hostserv> string +and B<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" + +=head1 SEE ALSO + +L<BIO_ADDRINFO(3)> + +=head1 COPYRIGHT + +Copyright 2016 The OpenSSL Project Authors.
