.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\& #include <openssl/ssl.h>
\&
\& 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,

.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBSSL_SESSION_has_ticket()\fR returns 1 if there is a Session Ticket associated with
this session, and 0 otherwise.
.PP
SSL_SESSION_get_ticket_lifetime_hint returns the lifetime hint in seconds
associated with the session ticket.
.PP
SSL_SESSION_get0_ticket obtains a pointer to the ticket associated with a
session. The length of the ticket is written to \fB*len\fR. If \fBtick\fR is non
NULL then a pointer to the ticket is written to \fB*tick\fR. 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 \fBSSL_CTX_flush_sessions()\fR.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBSSL_SESSION_has_ticket()\fR returns 1 if session ticket exists or 0 otherwise.
.PP
\&\fBSSL_SESSION_get_ticket_lifetime_hint()\fR returns the number of seconds.

.SH HISTORY
.IX Header "HISTORY"
The \fBSSL_SESSION_has_ticket()\fR, \fBSSL_SESSION_get_ticket_lifetime_hint()\fR
and \fBSSL_SESSION_get0_ticket()\fR functions were added in OpenSSL 1.1.0.
