SSL_CTX_SET_QUIET_SHUTDOWN(3)OpenSSLSSL_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(const SSL_CTX *ctx);

      void SSL_set_quiet_shutdown(SSL *ssl, int mode);
      int SSL_get_quiet_shutdown(const 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" set-
     ting 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 stan-
     dard.

     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.
