The state is internally 25maintained. Querying the state information is not very informative before 26or when a connection has been established. It however can be of significant 27interest during the handshake. 28 29When using non-blocking sockets, the function call performing the handshake 30may return with SSL_ERROR_WANT_READ or SSL_ERROR_WANT_WRITE condition, 31so that SSL_state_string[_long]() may be called. 32 33For both blocking or non-blocking sockets, the details state information 34can be used within the info_callback function set with the 35SSL_set_info_callback() call. 36 37=head1 RETURN VALUES 38 39Detailed description of possible states to be included later. 40 41=head1 SEE ALSO 42 43L<ssl(3)|ssl(3)>, L<SSL_CTX_set_info_callback(3)|SSL_CTX_set_info_callback(3)> 44 45=cut 46
