<h1><a name="name">NAME</a></h1>
<p>SSL_SESSION_get0_ticket,
SSL_SESSION_has_ticket, SSL_SESSION_get_ticket_lifetime_hint
- get details about the ticket associated with a session</p>
<p>
</p>
<hr />
<h1><a name="synopsis">SYNOPSIS</a></h1>
<pre>
#include <openssl/ssl.h></pre>
<pre>
int SSL_SESSION_has_ticket(const SSL_SESSION *s);
unsigned long SSL_SESSION_get_ticket_lifetime_hint(const SSL_SESSION *s);
void SSL_SESSION_get0_ticket(const SSL_SESSION *s, const unsigned char **tick,
size_t *len);</pre>

<h1><a name="description">DESCRIPTION</a></h1>
<p><code>SSL_SESSION_has_ticket()</code> returns 1 if there is a Session Ticket associated with
this session, and 0 otherwise.</p>
<p>SSL_SESSION_get_ticket_lifetime_hint returns the lifetime hint in seconds
associated with the session ticket.</p>
<p>SSL_SESSION_get0_ticket obtains a pointer to the ticket associated with a
session. The length of the ticket is written to <strong>*len</strong>. If <strong>tick</strong> is non
NULL then a pointer to the ticket is written to <strong>*tick</strong>. The pointer is only
valid while the connection is in use. The session (and hence the ticket pointer)
may also become invalid as a result of a call to <code>SSL_CTX_flush_sessions()</code>.</p>
<p>
</p>
<hr />
<h1><a name="return_values">RETURN VALUES</a></h1>
<p><code>SSL_SESSION_has_ticket()</code> returns 1 if session ticket exists or 0 otherwise.</p>
<p><code>SSL_SESSION_get_ticket_lifetime_hint()</code> returns the number of seconds.</p>
