I implemented reading of the output_size and output_buffer too. I couldn't
figure out how to actually run the CeRapiInvoke tests (my automake
experience is lacking) but I did create a separate executable that does the
same thing as those tests. It should pass test_ping_result and
test_ping_buffer now, but not the stream test (will still return
E_NOTIMPL). I didn't check test_last_error yet.
