void SSL_set_quiet_shutdown(SSL *ssl, int mode); int SSL_get_quiet_shutdown(const SSL *ssl);
SSL_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() 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() or SSL_set_quiet_shutdown()
is called again.
It is not changed when SSL_clear() is called.
mode may be 0 or 1.
SSL_get_quiet_shutdown()
returns the ``quiet shutdown'' setting of ssl.
Normally when a SSL connection is finished, the parties must send out ``close notify'' alert messages using SSL_shutdown() for a clean shutdown.
When setting the ``quiet shutdown'' flag to 1, SSL_shutdown() will set the internal flags to SSL_SENT_SHUTDOWN|SSL_RECEIVED_SHUTDOWN. (SSL_shutdown() then behaves like SSL_set_shutdown() 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.
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.
