# NAME

SSL_SESSION_get0_ticket, SSL_SESSION_has_ticket, SSL_SESSION_get_ticket_lifetime_hint - get details about the ticket associated with a session

# LIBRARY

libcrypto, -lcrypto

# SYNOPSIS

     #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,
                                  size_t *len);

# DESCRIPTION

SSL_SESSION_has_ticket() returns 1 if there is a Session Ticket associated with this session, and 0 otherwise.

SSL_SESSION_get_ticket_lifetime_hint returns the lifetime hint in seconds associated with the session ticket.

SSL_SESSION_get0_ticket obtains a pointer to the ticket associated with a session. The length of the ticket is written to *len. If tick is non NULL then a pointer to the ticket is written to *tick. 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 SSL_CTX_flush_sessions().

# RETURN VALUES

SSL_SESSION_has_ticket() returns 1 if session ticket exists or 0 otherwise.

SSL_SESSION_get_ticket_lifetime_hint() returns the number of seconds.
