#include <openssl/bio.h></pre>
<pre>
enum BIO_hostserv_priorities {
BIO_PARSE_PRIO_HOST, BIO_PARSE_PRIO_SERV

<h1><a name="description">DESCRIPTION</a></h1>
<p><code>BIO_parse_hostserv()</code> will parse the information given in <strong>hostserv</strong>,
create strings with the hostname and service name and give those
back via <strong>host</strong> and <strong>service</strong>. Those will need to be freed after
they are used. <strong>hostserv_prio</strong> helps determine if <strong>hostserv</strong> shall
be interpreted primarily as a hostname or a service name in ambiguous
cases.</p>
<p>The syntax the <code>BIO_parse_hostserv()</code> recognises is:</p>
<pre>
host + ':' + service
host + ':' + '*'
host + ':'
':' + service
'*' + ':' + service
host
service</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 <strong>hostserv</strong> string
and <strong>hostserv_prio</strong>, as follows:</p>
<pre>
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"</pre>
<pre>
in case no ':' is present in the string, the result depends on
hostserv_prio, as follows:</pre>
<pre>
when hostserv_prio == BIO_PARSE_PRIO_HOST
host => *host = "host", *service untouched</pre>
<pre>
when hostserv_prio == BIO_PARSE_PRIO_SERV
service => *host untouched, *service = "service"</pre>
<p>
</p>
<hr />
<h1><a name="return_values">RETURN VALUES</a></h1>
<p><code>BIO_parse_hostserv()</code> returns 1 on success or 0 on error.</p>
