=head1 NOTES
SSL_want() examines the internal state information of the SSL object. Its
return values are similar to that of L<SSL_get_error(3)|SSL_get_error(3)>.
Unlike L<SSL_get_error(3)|SSL_get_error(3)>, which also evaluates the
return values are similar to that of L<SSL_get_error(3)>.
Unlike L<SSL_get_error(3)>, which also evaluates the
error queue, the results are obtained by examining an internal state flag
only. The information must therefore only be used for normal operation under
non-blocking I/O. Error conditions are not handled and must be treated
using L<SSL_get_error(3)|SSL_get_error(3)>.
using L<SSL_get_error(3)>.
The result returned by SSL_want() should always be consistent with
the result of L<SSL_get_error(3)|SSL_get_error(3)>.

There are data in the SSL buffer that must be written to the underlying
B<BIO> layer in order to complete the actual SSL_*() operation.
A call to L<SSL_get_error(3)|SSL_get_error(3)> should return
A call to L<SSL_get_error(3)> should return
SSL_ERROR_WANT_WRITE.
=item SSL_READING
More data must be read from the underlying B<BIO> layer in order to
complete the actual SSL_*() operation.

A call to L<SSL_get_error(3)> should return

=item SSL_X509_LOOKUP
The operation did not complete because an application callback set by
SSL_CTX_set_client_cert_cb() has asked to be called again.
A call to L<SSL_get_error(3)|SSL_get_error(3)> should return

The asynchronous job could not be started because there were no async jobs
available in the pool (see ASYNC_init_thread(3)). A call to L<SSL_get_error(3)>
should return SSL_ERROR_WANT_ASYNC_JOB.
