- .SH 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);

- .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.
