=head1 SYNOPSIS
size_t SSL_get_num_tickets(SSL *s);
int SSL_CTX_set_num_tickets(SSL_CTX *ctx, size_t num_tickets);
size_t SSL_CTX_get_num_tickets(SSL_CTX *ctx);
+ int SSL_new_session_ticket(SSL *s);
=head1 DESCRIPTION
SSL_verify_client_post_handshake() to update the number of tickets that will be
sent.
+To issue tickets after other events (such as application-layer changes),
+SSL_new_session_ticket() is used by a server application to request that a new
+ticket be sent when it is safe to do so. New tickets are only allowed to be
+sent in this manner after the initial handshake has completed, and only for TLS
+1.3 connections. The ticket generation and transmission are delayed until the
+server is starting a new write operation, so that it is bundled with other
+application data being written and properly aligned to a record boundary.
+SSL_new_session_ticket() can be called more than once to request additional
+tickets be sent; all such requests are queued and written together when it is
+safe to do so. Note that a successful return from SSL_new_session_ticket()
+indicates only that the request to send a ticket was processed, not that the
+ticket itself was sent. To be notified when the ticket itself is sent, a
+new-session callback can be registered with L<SSL_CTX_sess_set_new_cb(3)> that
+will be invoked as the ticket or tickets are generated.
+
SSL_CTX_get_num_tickets() and SSL_get_num_tickets() return the number of
tickets set by a previous call to SSL_CTX_set_num_tickets() or
SSL_set_num_tickets(), or 2 if no such call has been made.
=head1 RETURN VALUES
-SSL_CTX_set_num_tickets() and SSL_set_num_tickets() return 1 on success or 0 on
-failure.
+SSL_CTX_set_num_tickets(), SSL_set_num_tickets(), and
+SSL_new_session_ticket() return 1 on success or 0 on failure.
SSL_CTX_get_num_tickets() and SSL_get_num_tickets() return the number of tickets
that have been previously set.
