SSL_CTX_set_quiet_shutd17/Aug/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
