SSL_CTX_flush_sessions(3)           OpenSSL          SSL_CTX_flush_sessions(3)



NAME
       SSL_CTX_flush_sessions, SSL_flush_sessions - remove expired sessions

LIBRARY
       libcrypto, -lcrypto

SYNOPSIS
        #include <openssl/ssl.h>

        void SSL_CTX_flush_sessions(SSL_CTX *ctx, long tm);
        void SSL_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.

       SSL_flush_sessions() is a synonym for SSL_CTX_flush_sessions().

NOTES
       If enabled, the internal session cache will collect all sessions estab-
       lished 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 expi-
       ration 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 inter-
       nal 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)).
