NAME

6       SSL_CTX_flush_sessions, SSL_flush_sessions - remove expired sessions
7

SYNOPSIS

9        #include <openssl/ssl.h>
10
11        void SSL_CTX_flush_sessions(SSL_CTX *ctx, long tm);
12        void SSL_flush_sessions(SSL_CTX *ctx, long tm);
13

DESCRIPTION

15       SSL_CTX_flush_sessions() causes a run through the session cache of ctx
16       to remove sessions expired at time tm.
17
18       SSL_flush_sessions() is a synonym for SSL_CTX_flush_sessions().
19

NOTES

21       If enabled, the internal session cache will collect all sessions
22       established up to the specified maximum number (see
23       SSL_CTX_sess_set_cache_size()).  As sessions will not be reused ones
24       they are expired, they should be removed from the cache to save
25       resources. This can either be done
26        automatically whenever 255 new sessions were established (see
27       SSL_CTX_set_session_cache_mode(3)) or manually by calling
28       SSL_CTX_flush_sessions().
29
30       The parameter tm specifies the time which should be used for the
31       expiration test, in most cases the actual time given by time(0) will be
32       used.
33
34       SSL_CTX_flush_sessions() will only check sessions stored in the
35       internal cache. When a session is found and removed, the
36       remove_session_cb is however called to synchronize with the external
37       cache (see SSL_CTX_sess_set_get_cb(3)).
