NAME    [Toc]    [Back]

       SSL_CTX_flush_sessions, SSL_flush_sessions - remove
       expired sessions

LIBRARY    [Toc]    [Back]

       libcrypto, -lcrypto

SYNOPSIS    [Toc]    [Back]

        #include <openssl/ssl.h>

        void SSL_CTX_flush_sessions(SSL_CTX *ctx, long tm);
        void SSL_flush_sessions(SSL_CTX *ctx, long tm);

DESCRIPTION    [Toc]    [Back]

       SSL_CTX_flush_sessions() causes a run through the session
       cache of ctx to remove sessions expired at time tm.

       SSL_flush_sessions() is a synonym for SSL_CTX_flush_ses-
       sions().

NOTES    [Toc]    [Back]

       If enabled, the internal session cache will collect all
       sessions established up to the specified maximum number
       (see SSL_CTX_sess_set_cache_size()).  As sessions will not
       be reused ones they are expired, they should be removed
       from the cache to save resources. This can either be done
        automatically whenever 255 new sessions were established
       (see SSL_CTX_set_session_cache_mode(3)) or manually by
       calling SSL_CTX_flush_sessions().

       The parameter tm specifies the time which should be used
       for the expiration test, in most cases the actual time
       given by time(0) will be used.

       SSL_CTX_flush_sessions() will only check sessions stored
       in the internal cache. When a session is found and
       removed, the remove_session_cb is however called to synchronize
 with the external cache (see
       SSL_CTX_sess_set_get_cb(3)).
