The shutdown state of the connection is used to determine the state of
the ssl session. If the session is still open, when
-L<SSL_clear(3)|SSL_clear(3)> or L<SSL_free(3)|SSL_free(3)> is called,
+L<SSL_clear(3)> or L<SSL_free(3)> is called,
it is considered bad and removed according to RFC2246.
The actual condition for a correctly closed session is SSL_SENT_SHUTDOWN
(according to the TLS RFC, it is acceptable to only send the "close notify"
alert but to not wait for the peer's answer, when the underlying connection
is closed).
SSL_set_shutdown() can be used to set this state without sending a
-close alert to the peer (see L<SSL_shutdown(3)|SSL_shutdown(3)>).
+close alert to the peer (see L<SSL_shutdown(3)>).
If a "close notify" was received, SSL_RECEIVED_SHUTDOWN will be set,
for setting SSL_SENT_SHUTDOWN the application must however still call
-L<SSL_shutdown(3)|SSL_shutdown(3)> or SSL_set_shutdown() itself.
+L<SSL_shutdown(3)> or SSL_set_shutdown() itself.
