However two questions: Why is it its own function and not part of stream_get_meta_data()? (which you anyway want to check to ensure that it's the proper stream type) Why are all resources throwing a TypeError and not only resources which aren't streams? I could imagine calling that function to check whether the stream is in memory or backed by a fd for example. I'd propose to return a proper checkable value like -1 in that case. Thanks, Bob
