SSL_CTX_flush_sessions - remove expired sessions
#include <openssl/ssl.h>
void SSL_CTX_flush_sessions(SSL_CTX *ctx, long tm);
SSL_CTX_flush_sessions() causes a run through the session cache of
ctx to remove sessions expired at time
tm.
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)).
SSL_CTX_flush_sessions() does not return a value.
