Also SEM_FAILCRITICALERRORS and other SEM_constants. They should as setting error mode on Windows for console applications is a pretty common use case (in fact ./Lib/test/libregrtest/setup.py uses it).

msvcrt set_error_mode, CrtReportMode, CrtReportFile and the associated CRT constants should be documented for use with debug builds. Also, msvcrt is missing the set_error_mode constants _OUT_TO_DEFAULT, _OUT_TO_STDERR, _OUT_TO_MSGBOX, and _REPORT_ERRMODE.
SetErrorMode 1 and the SEM_* constants are defined in msvcrt, for convenience I suppose. They're not related to the CRT. I think they should be aliased in the os module and documented there. GetErrorMode 2 can also be provided in Python 3.5+. It would be useful to also provide SetThreadErrorMode 3 and GetThreadErrorMode conditionally in Windows 7+, which is practically all Windows users nowadays.

Hi @eryksun , I have a question, the current Windows functions in the os module is normalized to
snake_caselike python functions. So if we want to alias to the os module, should we change the function name to something likeget_error_mode?aisk commentedon Sep 23, 2023
Another thought is the
SetErrorModeis only used in tests, so it was added in themsvcrt. But I think it's not so generic and widely used in theosmodule.I think move it to the
_winapiprivate module is more suitable?pythongh-74481: Add missing debug function docs and constants to msvc…
