     SSL_CTX_set_quiet_shutd0.9.6h (2001-SSL_CTX_set_quiet_shutdown(3)

     NAME
          SSL_CTX_set_quiet_shutdown, SSL_CTX_get_quiet_shutdown,
          SSL_set_quiet_shutdown, SSL_get_quiet_shutdown - manipulate
          shutdown behaviour

     SYNOPSIS
           #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
          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
          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.

     RETURN VALUES
          SSL_CTX_set_quiet_shutdown() and SSL_set_quiet_shutdown() do
          not return diagnostic information.
