SSL_CTX_set_quiet_shutdown(3)
NAME
  SSL_CTX_set_quiet_shutdown - Manipulate shutdown behavior

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
  The SSL_CTX_set_quiet_shutdown() function 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() or
  SSL_set_quiet_shutdown() is called again.  It is not changed when
  SSL_clear() is called.  mode may be 0 or 1.  SSL_get_quiet_shutdown()
  returns the "quiet shutdown" setting of ssl.

NOTES
  Normally when an SSL connection is finished, the parties must send out
  "close notify" alert messages using the SSL_shutdown() function for a clean
  shutdown. When setting the "quiet shutdown" flag to 1, SSL_shutdown() will
  set the internal flags to SSL_SENT_SHUTDOWN|SSL_RECEIVED_SHUTDOWN.  (The
  SSL_shutdown() function then behaves like SSL_set_shutdown() 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 behavior
  violates the TLS standard. The default is normal shutdown behavior as
  described by the TLS standard.

RETURN VALUES
  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() return the current setting.
