SSL objects already created with 20L<SSL_new(3)|SSL_new(3)> are not affected, except when 21L<SSL_clear(3)|SSL_clear(3)> is being called. 22 23SSL_set_ssl_method() sets a new TLS/SSL B<method> for a particular B<ssl> 24object. It may be reset, when SSL_clear() is called. 25 26SSL_get_ssl_method() returns a function pointer to the TLS/SSL method 27set in B<ssl>. 28 29=head1 NOTES 30 31The available B<method> choices are described in 32L<SSL_CTX_new(3)|SSL_CTX_new(3)>. 33 34When L<SSL_clear(3)|SSL_clear(3)> is called and no session is connected to 35an SSL object, the method of the SSL object is reset to the method currently 36set in the corresponding SSL_CTX object. 37 38=head1 RETURN VALUES 39 40The following return values can occur for SSL_CTX_set_ssl_version() 41and SSL_set_ssl_method(): 42 43=over 4 44 45=item Z<>0 46 47The new choice failed, check the error stack to find out the reason. 48 49=item Z<>1 50 51The operation succeeded. 52 53=back 54 55=head1 SEE ALSO 56 57L<SSL_CTX_new(3)|SSL_CTX_new(3)>, L<SSL_new(3)|SSL_new(3)>, 58L<SSL_clear(3)|SSL_clear(3)>, L<ssl(3)|ssl(3)>, 59L<SSL_set_connect_state(3)|SSL_set_connect_state(3)> 60 61=cut 62
