     ciphers, BIOs) are kept.

     SSL_clear is used to prepare an SSL object for a new
     connection. While all settings are kept, a side effect is
     the handling of the current SSL session.  If a session is
     still ooooppppeeeennnn, it is considered bad and will be removed from
     the session cache, as required by RFC2246. A session is
     considered open, if SSL_shutdown(3) was not called for the
     connection or at least SSL_set_shutdown(3) was used to set
     the SSL_SENT_SHUTDOWN state.

     If a session was closed cleanly, the session object will be
     kept and all settings corresponding. This explicitly means,
     that e.g. the special method used during the session will be
     kept for the next handshake. So if the session was a TLSv1
     session, a SSL client object will use a TLSv1 client method
     for the next handshake and a SSL server object will use a
     TLSv1 server method, even if SSLv23_*_methods were chosen on
     startup. This will might lead to connection failures (see
     SSL_new(3)) for a description of the method's properties.

WWWWAAAARRRRNNNNIIIINNNNGGGGSSSS
     SSL_clear() resets the SSL object to allow for another
     connection. The reset operation however keeps several
     settings of the last sessions (some of these settings were
     made automatically during the last handshake). It only makes
     sense when opening a new session (or reusing an old one)
     with the same peer that shares these settings.  SSL_clear()
     is not a short form for the sequence SSL_free(3);
     SSL_new(3); .

     The following return values can occur:

     0   The SSL_clear() operation could not be performed. Check
         the error stack to find out the reason.

     1   The SSL_clear() operation was successful.
