     NAME
          SSL_CTX_flush_sessions, SSL_flush_sessions - remove expired
          sessions

     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 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)).
