     SSL_CTX_set_quiet_shutdown() sets the "quiet shutdown" flag
     for ccccttttxxxx to be mmmmooooddddeeee. SSL objects created from ccccttttxxxx inherit the
     mmmmooooddddeeee valid at the time SSL_new(3) is called. mmmmooooddddeeee may be 0
     or 1.

     SSL_CTX_get_quiet_shutdown() returns the "quiet shutdown"
     setting of ccccttttxxxx.

     SSL_set_quiet_shutdown() sets the "quiet shutdown" flag for
     ssssssssllll to be mmmmooooddddeeee. The setting stays valid until ssssssssllll is removed
     with SSL_free(3) or SSL_set_quiet_shutdown() is called
     again.  It is not changed when SSL_clear(3) is called.  mmmmooooddddeeee
     may be 0 or 1.

     SSL_get_quiet_shutdown() returns the "quiet shutdown"
     setting of ssssssssllll.

     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_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.
