Summary 0001021: fwprintf EOVERFLOW
Description The description[1] of fwprintf family of functions (please note "w" in the name) mentions EOVERFLOW as applicable to swprintf only. The same problem was reported and fixed for fprintf family (without "w" in the name) in the issue #316[2]. Similar fixes should be applied to fwprintf.

[1] http://pubs.opengroup.org/onlinepubs/9699919799/functions/fwprintf.html [^]
[2] http://austingroupbugs.net/view.php?id=316 [^]

P.S. http://austingroupbugs.net/view.php?id=761 [^] is also applicable to fwprintf.

P.P.S. The "Return value" part of the description reads: "or a negative value if an output error was encountered". However errors are not strictly limited to output. E.g. C11 reads: "or a negative value
if an output or encoding error occurred" (please note "or encoding" part). This is not very important given that EILSEQ is mentioned in the "Error" part of the description but if someone thinks this warrants a separate bug report please let me know or just file. fprintf is affected too.
Desired Action Fix the fwprintf description similar to http://austingroupbugs.net/view.php?id=316 [^] .

 Interpretation response
------------------------

The standard states the requirements for the error handling for the
wprintf family of functions, and conforming implementations must conform
to this. However, concerns have been raised about this which are being
referred to the sponsor.

Rationale:
-------------
None.

Notes to the Editor (not part of this interpretation):
-------------------------------------------------------

On (2016 edition) page 915 line 31020 section fprintf() change:
If an output error was encountered
to:
If an error was encountered

On (2016 edition) page 998 line 33977 section fwprintf() change:
if an output error was encountered
to:
if an error was encountered

On (2016 edition) page 998 line 33982 add:
[EOVERFLOW]
[CX] The value to be returned is greater than {INT_MAX}.[/CX]

On (2016 edition) page 999 line 33988 change:
The value of n is greater than {INT_MAX} or the number of bytes needed to hold the output excluding the terminating null is greater than {INT_MAX}.
to:
The value of n is greater than {INT_MAX}.
