Yes, I did overlook something.
When working with socket streams provided by _fdopen, Nut/OS internally works with the NUTVIRTUALDEVICE structure. By calling fclose on these streams Nut/OS doesn't call _close but calls _write(n, 0, 0). And that causes a output buffer flush.

That means, the output buffer from TCP sockets IS flushed by calling fclose.

Sorry, but these device, files, virtuals stuff is gonna be getting a little bit complicated... Never mind.


Merry Christmas and a happy new year.
Oliver.
