Those will need to be freed after they are used. <b>hostserv_prio</b> helps determine if <b>hostserv</b> shall be interpreted primarily as a hostname or a service name in ambiguous cases.</p> <p>The syntax the BIO_parse_hostserv() recognises is:</p> <pre><code> host + ':' + service host + ':' + '*' host + ':' ':' + service '*' + ':' + service host service</code></pre> <p>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]'.</p> <p>The service part can be a service name or its port number.</p> <p>The returned values will depend on the given <b>hostserv</b> string and <b>hostserv_prio</b>, as follows:</p> <pre><code> 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"</code></pre> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>BIO_parse_hostserv() returns 1 on success or 0 on error.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/BIO_ADDRINFO.html">BIO_ADDRINFO(3)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2016-2020 The OpenSSL Project Authors.
