DESCRIPTIONSSL_CTX_set_quiet_shutdown() sets the ``quiet shutdown'' flag for ctx to be mode. SSL objects created from ctx inherit the mode valid at the time SSL_new(3) is called. mode may be 0 or 1.
SSL_CTX_get_quiet_shutdown() returns the ``quiet shutdown'' setting of ctx.
SSL_set_quiet_shutdown() sets the ``quiet shutdown'' flag for ssl to be mode. The setting stays valid until ssl is removed with SSL_free(3) or SSL_set_quiet_shutdown() is called again. It is not changed when SSL_clear(3) is called. mode may be 0 or 1.
SSL_get_quiet_shutdown() returns the ``quiet shutdown'' setting of ssl.
NOTESNormally when a SSL connection is finished, the parties must send out ``close notify'' alert messages using SSL_shutdown(3) for a clean shutdown.
When setting the ``quiet shutdown'' flag to 1, SSL_shutdown(3) will set the internal flags to SSL_SENT_SHUTDOWN|SSL_RECEIVED_SHUTDOWN. (SSL_shutdown(3) then behaves like 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.
RETURN VALUESSSL_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.
