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
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)).
