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" 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.
