Are you saying that there's only one of these AttributeInfo structures
in the reply in question? I'm pretty sure this case works fine if you
return a list of AttributeInfos; and I suspect it would happen to be OK
for a single AttributeInfo as long as it's the last thing in the reply.

getenv("DISPLAY") is the only answer I have to that question... but what
are you trying to do? If you want the screen number out of the DISPLAY,
for example, you should save it yourself when opening the XCBConnection.
