SSL objects created from B<ctx> inherit the B<mode> valid at the time +L<SSL_new(3)> is called. B<mode> may be 0 or 1. + +SSL_CTX_get_quiet_shutdown() returns the "quiet shutdown" setting of B<ctx>. + +SSL_set_quiet_shutdown() sets the "quiet shutdown" flag for B<ssl> to be +B<mode>. The setting stays valid until B<ssl> is removed with +L<SSL_free(3)> or SSL_set_quiet_shutdown() is called again. +It is not changed when L<SSL_clear(3)> is called. +B<mode> may be 0 or 1. + +SSL_get_quiet_shutdown() returns the "quiet shutdown" setting of B<ssl>. + +=head1 NOTES + +Normally when a SSL connection is finished, the parties must send out +close_notify alert messages using L<SSL_shutdown(3)> +for a clean shutdown. + +When setting the "quiet shutdown" flag to 1, L<SSL_shutdown(3)> +will set the internal flags to SSL_SENT_SHUTDOWN|SSL_RECEIVED_SHUTDOWN. +(L<SSL_shutdown(3)> then behaves like +L<SSL_set_shutdown(3)> 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. + +The default is normal shutdown behaviour as described by the TLS standard. + +=head1 RETURN VALUES + +SSL_CTX_set_quiet_shutdown() and SSL_set_quiet_shutdown() do not return +diagnostic information. + +SSL_CTX_get_quiet_shutdown() and SSL_get_quiet_shutdown return the current +setting. + +=head1 SEE ALSO + +L<ssl(7)>, L<SSL_shutdown(3)>, +L<SSL_set_shutdown(3)>, L<SSL_new(3)>, +L<SSL_clear(3)>, L<SSL_free(3)> + +=head1 COPYRIGHT + +Copyright 2001-2018 The OpenSSL Project Authors.
