212\fISSL_set_quiet_shutdown()\fR sets the \*(L"quiet shutdown\*(R" flag for \fBssl\fR to be

984263bc
MD
214SSL_free(3) or \fISSL_set_quiet_shutdown()\fR is called again.
215It is not changed when SSL_clear(3) is called.

984263bc 219.SH "NOTES"
a7d27d5a
JR
220Normally when a SSL connection is finished, the parties must send out
221\*(L"close notify\*(R" alert messages using SSL_shutdown(3)
984263bc
MD
222for a clean shutdown.
223.PP
224When setting the \*(L"quiet shutdown\*(R" flag to 1, SSL_shutdown(3)
225will set the internal flags to SSL_SENT_SHUTDOWN|SSL_RECEIVED_SHUTDOWN.
226(SSL_shutdown(3) then behaves like
227SSL_set_shutdown(3) called with
228SSL_SENT_SHUTDOWN|SSL_RECEIVED_SHUTDOWN.)
229The session is thus considered to be shutdown, but no \*(L"close notify\*(R" alert
a7d27d5a 230is sent to the peer. This behaviour violates the TLS standard.
984263bc 231.PP
a7d27d5a 232The default is normal shutdown behaviour as described by the TLS standard.
984263bc 233.SH "RETURN VALUES"
