Wrong value for |FileNormalizedNameInfo| (|24| vs. |48|) in Cygwin 3.6 /usr/include ...

Wrong value for |FileNormalizedNameInfo| (|24| vs. |48|) in Cygwin 3.6 /usr/include ...

[Roland Mainz]

Hi!

----

I'm writing a test program for |FileNormalizedNameInfo| right now (see
https://rovema.kpaste.net/07074abc).

Per https://learn.microsoft.com/en-us/windows/win32/api/minwinbase/ne-minwinbase-file_info_by_handle_class
|FileNormalizedNameInfo| should be |24|, but on Cygwin 3.6 I get the
value |48|.
Since |GetFileInformationByHandleEx()| gives me error 87 (="Invalid
Parameter") for |48|, but works as intended for |24| I assume that the
Cygwin header is wrong.

Could someone please check the Cygwin header files ?

Headers:
---- snip ----
$ grep -r FileNormalizedNameInfo /usr/include/
/usr/include/w32api/ddk/wdm.h:  FileNormalizedNameInformation,
/usr/include/w32api/minwinbase.h:    FileNormalizedNameInfo,
/usr/include/w32api/winternl.h:    FileNormalizedNameInformation = 48,
---- snip ----

Cygwin version:
---- snip ----
$ uname -a
CYGWIN_NT-10.0-19045 okkoto 3.6.0-0.115.g579064bf4d40.x86_64
2024-04-09 21:11 UTC x86_64 Cygwin
---- snip ----

Bye,
Roland

Could someone please read the enum constant names and classes carefully?

Package w32api-headers:

*FileNormalizedNameInfo* 24/0x18 is defined in minwinbase.h 
FILE_INFO_BY_HANDLE_CLASS for GetFileInformationByHandleEx whereas 
*FileNormalizedNameInformation* 44/0x2e is defined in winternl.h 
FILE_INFORMATION_CLASS for NtQueryInformationFile:

https://learn.microsoft.com/en-us/windows-hardware/drivers/ddi/ntifs/nf-ntifs-ntqueryinformationfile

ditto in ddk/wdm.h!

Something is still wrong on my side, with Cygwin 3.6 on Windows 10:

Example:
---- snip ----
#define UNICODE 1
#define _UNICODE 1

#include <stdio.h>
#include <windows.h>
#include <stdlib.h>
#include <stdbool.h>

int main(int ac, char *av[])
{
    (void)printf("FileNormalizedNameInfo=%d/0x%x\n",
        (int)FileNormalizedNameInfo,
        (int)FileNormalizedNameInfo);

    return EXIT_SUCCESS;
}
---- snip ----

Compiling this with $ gcc -Wall test4.c -o test4 # and running it returns this:
---- snip ----
$ ./test4
FileNormalizedNameInfo=22/0x16
---- snip ----
The expected output would be "FileNormalizedNameInfo=24/0x18", because
in https://learn.microsoft.com/de-de/windows/win32/api/minwinbase/ne-minwinbase-file_info_by_handle_class
|FileNormalizedNameInfo| is in position 24.

Looking at /usr/include/w32api/minwinbase.h:
---- snip ----
  typedef enum _FILE_INFO_BY_HANDLE_CLASS {
   FileBasicInfo /* is zero? */,
   FileStandardInfo,
   FileNameInfo,
   FileRenameInfo,
   FileDispositionInfo,
   FileAllocationInfo,
   FileEndOfFileInfo,
   FileStreamInfo,
   FileCompressionInfo,
   FileAttributeTagInfo,
   FileIdBothDirectoryInfo,
   FileIdBothDirectoryRestartInfo,
   FileIoPriorityHintInfo,
   FileRemoteProtocolInfo,
   FileFullDirectoryInfo,
   FileFullDirectoryRestartInfo,
#if _WIN32_WINNT >= 0x0602
   FileStorageInfo,
   FileAlignmentInfo,
   FileIdInfo,
   FileIdExtdDirectoryInfo,
   FileIdExtdDirectoryRestartInfo,
#endif
#if _WIN32_WINNT >= 0x0A000002
   FileDispositionInfoEx,
   FileRenameInfoEx,
#endif
   FileCaseSensitiveInfo,
   FileNormalizedNameInfo,
   MaximumFileInfoByHandleClass
 } FILE_INFO_BY_HANDLE_CLASS, *PFILE_INFO_BY_HANDLE_CLASS;
#endif
---- snip ----

This code cannot work, because the integer value for
|FileNormalizedNameInfo| enum shift with different Windows versions,
e.g. |FileNormalizedNameInfo| has value |22| if |_WIN32_WINNT==0x0602|
but value |24| if |_WIN32_WINNT==0x0A000002|.

I filed https://github.com/mingw-w64/mingw-w64/issues/48 for the
issue, but it would be nice if this can be fixed in both Cygwin 3.5
and 3.6...

Bye,

Good catch and point!
My computer glasses did not seem to be working well last weekend!

FWIW, this is how it is defined by the native M$ SDK:

#if (NTDDI_VERSION >= NTDDI_LONGHORN)
typedef enum _FILE_INFO_BY_HANDLE_CLASS {
    FileBasicInfo,
    FileStandardInfo,
    FileNameInfo,
    FileRenameInfo,
    FileDispositionInfo,
    FileAllocationInfo,
    FileEndOfFileInfo,
    FileStreamInfo,
    FileCompressionInfo,
    FileAttributeTagInfo,
    FileIdBothDirectoryInfo,
    FileIdBothDirectoryRestartInfo,
    FileIoPriorityHintInfo,
    FileRemoteProtocolInfo,
    FileFullDirectoryInfo,
    FileFullDirectoryRestartInfo,
#if (NTDDI_VERSION >= NTDDI_WIN8)
    FileStorageInfo,
    FileAlignmentInfo,
    FileIdInfo,
    FileIdExtdDirectoryInfo,
    FileIdExtdDirectoryRestartInfo,
#endif
#if (NTDDI_VERSION >= NTDDI_WIN10_RS1)
    FileDispositionInfoEx,
    FileRenameInfoEx,
#endif
#if (NTDDI_VERSION >= NTDDI_WIN10_19H1)
    FileCaseSensitiveInfo,
    FileNormalizedNameInfo,
#endif
    MaximumFileInfoByHandleClass
} FILE_INFO_BY_HANDLE_CLASS, *PFILE_INFO_BY_HANDLE_CLASS;
#endif
