  77. .SH DESCRIPTION
  78. .IX Header "DESCRIPTION"
  79. \&\fBSSL_SESSION_has_ticket()\fR returns 1 if there is a Session Ticket associated with
  80. this session, and 0 otherwise.
  81. .PP
  82. SSL_SESSION_get_ticket_lifetime_hint returns the lifetime hint in seconds
  83. associated with the session ticket.
  84. .PP
  85. SSL_SESSION_get0_ticket obtains a pointer to the ticket associated with a
  86. session. The length of the ticket is written to \fB*len\fR. If \fBtick\fR is non
  87. NULL then a pointer to the ticket is written to \fB*tick\fR. The pointer is only
  88. valid while the connection is in use. The session (and hence the ticket pointer)
  89. may also become invalid as a result of a call to \fBSSL_CTX_flush_sessions()\fR.
  90. .SH "RETURN VALUES"
  91. .IX Header "RETURN VALUES"
  92. \&\fBSSL_SESSION_has_ticket()\fR returns 1 if session ticket exists or 0 otherwise.
  93. .PP
  94. \&\fBSSL_SESSION_get_ticket_lifetime_hint()\fR returns the number of seconds.

  103. The \fBSSL_SESSION_has_ticket()\fR, \fBSSL_SESSION_get_ticket_lifetime_hint()\fR
  104. and \fBSSL_SESSION_get0_ticket()\fR functions were added in OpenSSL 1.1.0.
