Can some example code be added to the RFC text for those who don't 
understand any French?

Hey George,

I like the idea. 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

[G. P. B.]

Hello internals,

I would like to start the discussion about the "Add file_descriptor()
function" RFC:
https://wiki.php.net/rfc/file-descriptor-function

This RFC proposes the addition of the file_descriptor() function to
retrieve the underlying file descriptor of stream if it exists. This is
useful when interacting with a USB device.

Best regards,
