It would be best if we followed the current style conventions in new code instead of adding more code using the old ones. Specifically: - Just an "Unexpected hr %#lx.\n" (or "name", or whatever the message calls for) is an appropriate ok() message - No need for the if (SUCCEEDED(hr)) {}, this is never supposed to fail - '{' on its own line - !container instead of == NULL

Can you please initialize this to 0xdeadbeefu or so? Just to clarify that it's somehow not initialized by the function to ~0u (which would be weird but not as much as a 0xdeadbeef value...)

Same as above (!var instead of var == 0, '{' on its own line), but additionally please put the if () body on its own line.

I prefer to have brackets around multiline (even though single statement) blocks.
This looks mostly good, I only left a bunch of minor comments.
