SSL_CTX_SET_QUIET_SHUTDOWN(3)OpenSSLSSL_CTX_SET_QUIET_SHUTDOWN(3)

NAME    [Toc]    [Back]

       SSL_CTX_set_quiet_shutdown, SSL_CTX_get_quiet_shutdown,
       SSL_set_quiet_shutdown, SSL_get_quiet_shutdown - manipulate
 shutdown behaviour

SYNOPSIS    [Toc]    [Back]

        #include <openssl/ssl.h>

        void SSL_CTX_set_quiet_shutdown(SSL_CTX *ctx, int mode);
        int SSL_CTX_get_quiet_shutdown(SSL_CTX *ctx);

        void SSL_set_quiet_shutdown(SSL *ssl, int mode);
        int SSL_get_quiet_shutdown(SSL *ssl);

DESCRIPTION    [Toc]    [Back]

       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(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.

NOTES    [Toc]    [Back]

       Normally 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_shutdow
 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 VALUES    [Toc]    [Back]

       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
SSL_CTX_SET_QUIET_SHUTDOWN(3)OpenSSLSSL_CTX_SET_QUIET_SHUTDOWN(3)


       return the current setting.
