SSL_SESSION_get_time3ssl

Usage

 #include <openssl/ssl.h>
 long SSL_SESSION_get_timeout(const SSL_SESSION *s);
 long SSL_SESSION_set_timeout(SSL_SESSION *s, long tm);
 long SSL_get_timeout(const SSL_SESSION *s);
 long SSL_set_timeout(SSL_SESSION *s, long tm);
 time_t SSL_SESSION_get_time_ex(const SSL_SESSION *s);
 time_t SSL_SESSION_set_time_ex(SSL_SESSION *s, time_t tm);

 long SSL_SESSION_get_time(const SSL_SESSION *s);
 long SSL_SESSION_set_time(SSL_SESSION *s, long tm);
 long SSL_get_time(const SSL_SESSION *s);
 long SSL_set_time(SSL_SESSION *s, long tm);

Overview

SSL_SESSION_get_time_ex() returns the time at which the session s was established. The time is given in seconds since the Epoch and therefore compatible to the time delivered by the time() call.

SSL_SESSION_set_time_ex() replaces the creation time of the session s with the chosen value tm.

SSL_SESSION_get_timeout() returns the timeout value set for session s in seconds.

SSL_SESSION_set_timeout() sets the timeout value for session s in seconds to tm.

SSL_SESSION_get_time() and SSL_SESSION_set_time() functions use the long datatype instead of time_t and are therefore deprecated due to not being Y2038-safe on 32 bit systems. Note that such systems still need to be configured to use 64 bit time_t to be able to avoid overflow in system time.

The SSL_get_time(), SSL_set_time(), SSL_get_timeout(), and SSL_set_timeout() functions are synonyms for the SSL_SESSION_*() counterparts.

Notes

Sessions are expired by examining the creation time and the timeout value. Both are set at creation time of the session to the actual time and the default timeout value at creation, respectively, as set by SSL_CTX_set_timeout(3). Using these functions it is possible to extend or shorten the lifetime of the session.

Return values

SSL_SESSION_get_time_ex() and SSL_SESSION_get_timeout() return the currently valid values.

SSL_SESSION_set_time_ex() returns time on success.

SSL_SESSION_set_timeout() returns 1 on success.

If any of the function is passed the NULL pointer for the session s, 0 is returned.
