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.
