984263bc
MD
208The shutdown state of an ssl connection is a bitmask of:
209.Ip "0" 4
210No shutdown setting, yet.
211.Ip "\s-1SSL_SENT_SHUTDOWN\s0" 4
984263bc
MD
212A \*(L"close notify\*(R" shutdown alert was sent to the peer, the connection is being
213considered closed and the session is closed and correct.
214.Ip "\s-1SSL_RECEIVED_SHUTDOWN\s0" 4
984263bc
MD
215A shutdown alert was received form the peer, either a normal \*(L"close notify\*(R"
216or a fatal error.
217.PP
a7d27d5a 218\s-1SSL_SENT_SHUTDOWN\s0 and \s-1SSL_RECEIVED_SHUTDOWN\s0 can be set at the same time.
984263bc
MD
219.PP
220The shutdown state of the connection is used to determine the state of
221the ssl session. If the session is still open, when
222SSL_clear(3) or SSL_free(3) is called,
223it is considered bad and removed according to \s-1RFC2246\s0.
224The actual condition for a correctly closed session is \s-1SSL_SENT_SHUTDOWN\s0
225(according to the \s-1TLS\s0 \s-1RFC\s0, it is acceptable to only send the \*(L"close notify\*(R"
226alert but to not wait for the peer's answer, when the underlying connection
227is closed).
a7d27d5a 228\fISSL_set_shutdown()\fR can be used to set this state without sending a
984263bc
MD
229close alert to the peer (see SSL_shutdown(3)).
230.PP
231If a \*(L"close notify\*(R" was received, \s-1SSL_RECEIVED_SHUTDOWN\s0 will be set,
232for setting \s-1SSL_SENT_SHUTDOWN\s0 the application must however still call
233SSL_shutdown(3) or \fISSL_set_shutdown()\fR itself.
234.SH "RETURN VALUES"
a7d27d5a 235\fISSL_set_shutdown()\fR does not return diagnostic information.
984263bc 236.PP
a7d27d5a 237\fISSL_get_shutdown()\fR returns the current setting.
