863. What is the state of a stream after close() succeedsSection: 31.10 [file.streams] Status: NAD Submitter: Steve Clamage Opened: 2008-07-08 Last modified: 2017-06-15

Discussion:
Suppose writing to an [o]fstream fails and you later close the stream. The overflow() function is called to flush the buffer (if it exists). Then the file is unconditionally closed, as if by calling flcose.
If either overflow or fclose fails, close() reports failure, and clearly the stream should be in a failed or bad state.
Suppose the buffer is empty or non-existent (so that overflow() does not fail), and fclose succeeds. The close() function reports success, but what is the state of the stream?
[ Batavia (2009-05): ]
Tom's impression is that the issue is about the
failbit, etc.Bill responds that the stream is now closed, and any status bits remain unchanged.
See the description of
close()in 31.10.6.4 [fstream.members].We prefer not to add wording to say that nothing changes. Move to NAD.
