SSL_CTX_FLUSH_SESSIONS(3)            OpenSSL           SSL_CTX_FLUSH_SESSIONS(3)



NAME
       SSL_CTX_flush_sessions - remove expired sessions

SYNOPSIS
        #include <openssl/ssl.h>

        void SSL_CTX_flush_sessions(SSL_CTX *ctx, long tm);

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

NOTES
       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)).

RETURN VALUES
       SSL_CTX_flush_sessions() does not return a value.
