<CODE>SSL_CTX_set_quiet_shutdown()</CODE> sets the ``quiet shutdown'' flag
for <STRONG>ctx</STRONG> to be
<STRONG>mode</STRONG>. SSL objects created from <STRONG>ctx</STRONG> inherit the <STRONG>mode</STRONG> valid at the time
<A HREF="../ssl/SSL_new.html#">SSL_new(3)</A> is called. <STRONG>mode</STRONG> may be 0 or 1.

</P>
<P>
<CODE>SSL_CTX_get_quiet_shutdown()</CODE> returns the ``quiet shutdown''
setting of <STRONG>ctx</STRONG>.

</P>
<P>
<CODE>SSL_set_quiet_shutdown()</CODE> sets the ``quiet shutdown'' flag for <STRONG>ssl</STRONG> to be
<STRONG>mode</STRONG>. The setting stays valid until <STRONG>ssl</STRONG> is removed with
<A HREF="../ssl/SSL_free.html#">SSL_free(3)</A> or <CODE>SSL_set_quiet_shutdown()</CODE> is called again. It is not changed
when <A HREF="../ssl/SSL_clear.html#">SSL_clear(3)</A> is called.
<STRONG>mode</STRONG> may be 0 or 1.

</P>
<P>
<CODE>SSL_get_quiet_shutdown()</CODE> returns the ``quiet shutdown''
setting of <STRONG>ssl</STRONG>.

<P>
Normally when a SSL connection is finished, the parties must send out
``close notify'' alert messages using <A HREF="../ssl/SSL_shutdown.html#">SSL_shutdown(3)</A>
for a clean shutdown.

</P>
<P>
When setting the ``quiet shutdown'' flag to 1, <A HREF="../ssl/SSL_shutdown.html#">SSL_shutdown(3)</A>
will set the internal flags to SSL_SENT_SHUTDOWN|SSL_RECEIVED_SHUTDOWN. (<A HREF="../ssl/SSL_shutdown.html#">SSL_shutdown(3)</A> then behaves like
<A HREF="../ssl/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.

the current setting.
