SSL objects created from <b>ctx</b> inherit the <b>mode</b> valid at the time <a href="../man3/SSL_new.html">SSL_new(3)</a> is called. <b>mode</b> may be 0 or 1.</p> <p>SSL_CTX_get_quiet_shutdown() returns the "quiet shutdown" setting of <b>ctx</b>.</p> <p>SSL_set_quiet_shutdown() sets the "quiet shutdown" flag for <b>ssl</b> to be <b>mode</b>. The setting stays valid until <b>ssl</b> is removed with <a href="../man3/SSL_free.html">SSL_free(3)</a> or SSL_set_quiet_shutdown() is called again. It is not changed when <a href="../man3/SSL_clear.html">SSL_clear(3)</a> is called. <b>mode</b> may be 0 or 1.</p> <p>SSL_get_quiet_shutdown() returns the "quiet shutdown" setting of <b>ssl</b>.</p> <h1 id="NOTES">NOTES</h1> <p>Normally when a SSL connection is finished, the parties must send out close_notify alert messages using <a href="../man3/SSL_shutdown.html">SSL_shutdown(3)</a> for a clean shutdown.</p> <p>When setting the "quiet shutdown" flag to 1, <a href="../man3/SSL_shutdown.html">SSL_shutdown(3)</a> will set the internal flags to SSL_SENT_SHUTDOWN|SSL_RECEIVED_SHUTDOWN. (<a href="../man3/SSL_shutdown.html">SSL_shutdown(3)</a> then behaves like <a href="../man3/SSL_set_shutdown.html">SSL_set_shutdown(3)</a> called with SSL_SENT_SHUTDOWN|SSL_RECEIVED_SHUTDOWN.) The session is thus considered to be shutdown, but no close_notify alert is sent to the peer. This behaviour violates the TLS standard.</p> <p>The default is normal shutdown behaviour as described by the TLS standard.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>SSL_CTX_set_quiet_shutdown() and SSL_set_quiet_shutdown() do not return diagnostic information.</p> <p>SSL_CTX_get_quiet_shutdown() and SSL_get_quiet_shutdown return the current setting.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man7/ssl.html">ssl(7)</a>, <a href="../man3/SSL_shutdown.html">SSL_shutdown(3)</a>, <a href="../man3/SSL_set_shutdown.html">SSL_set_shutdown(3)</a>, <a href="../man3/SSL_new.html">SSL_new(3)</a>, <a href="../man3/SSL_clear.html">SSL_clear(3)</a>, <a href="../man3/SSL_free.html">SSL_free(3)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2001-2018 The OpenSSL Project Authors.
