=head1 SYNOPSIS
int SSL_want_read(const SSL *ssl);

+ int SSL_want_async(const SSL *ssl);
+ int SSL_want_async_job(const SSL *ssl);
=head1 DESCRIPTION
=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)>.
+the result of L<SSL_get_error(3)>.
=head1 RETURN VALUES
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)|SSL_get_error(3)> should return
+A call to L<SSL_get_error(3)> should return
SSL_ERROR_WANT_READ.
=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
+A call to L<SSL_get_error(3)> should return
SSL_ERROR_WANT_X509_LOOKUP.
+=item SSL_ASYNC_PAUSED
+
+An asynchronous operation partially completed and was then paused. See
+L<SSL_get_all_async_fds(3)>. A call to L<SSL_get_error(3)> should return
+SSL_ERROR_WANT_ASYNC.
+
+=item SSL_ASYNC_NO_JOBS
+
+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.

=back
-SSL_want_nothing(), SSL_want_read(), SSL_want_write(), SSL_want_x509_lookup()
-return 1, when the corresponding condition is true or 0 otherwise.
+SSL_want_nothing(), SSL_want_read(), SSL_want_write(), SSL_want_x509_lookup(),
+SSL_want_async() and SSL_want_async_job() return 1, when the corresponding
+condition is true or 0 otherwise.
