error C2143: syntax error: missing ':' before 'constant'

[ForNow]

I am getting an error in a windows include winioctl.h

typedef union {
USN_RECORD_COMMON_HEADER Header;
USN_RECORD_V2 V2; <===
USN_RECORD_V3 V3; <===
USN_RECORD_V4 V4; <====
} USN_RECORD_UNION, *PUSN_RECORD_UNION;

for the 3 lines pointed to by the errors the code built find with the windows sdk 8 I migrated the application to windows 10 and am using the windows 10 sdk Thanks

And that error would be what?

C2143 syntax error missing ':' before constant the error might make sense if

USN_RECORD_COMMON_HEADER

wasn't defined but it is a few lines above

[Peter_in_2780]

But are USN_RECORD_V2 USN_RECORD_V3 USN_RECORD_V4 defined? That's where I'd look, given your original error messages.

Software rusts. Simon Stephenson, ca 1994. So does this signature. me, 2012

Could you post these "few lines"?

Have a look in Winioctl.h to check the definitions of these types. My version compiles them fine on VS2017 and Windows 10.

Check the typedefs of the three structures that fail for mutual non standard members. A candidate is the USN member. Do you have a define directive using the same name anywhere in your project? If that does not help enable the creation of preprocessor output files. Then you can check what the compiler "sees".

[ForNow]

Here is the definition USN_RECORD_COMMON_HEADER

typedef struct {
DWORD RecordLength;
WORD MajorVersion;
WORD MinorVersion;
} USN_RECORD_COMMON_HEADER, *PUSN_RECORD_COMMON_HEADER;

[ForNow]

typedef USN_RECORD_V2 USN_RECORD, *PUSN_RECORD;

typedef struct {

DWORD RecordLength;
WORD   MajorVersion;
WORD   MinorVersion;
FILE\_ID\_128 FileReferenceNumber;
FILE\_ID\_128 ParentFileReferenceNumber;
USN Usn;
LARGE\_INTEGER TimeStamp;
DWORD Reason;
DWORD SourceInfo;
DWORD SecurityId;
DWORD FileAttributes;
WORD   FileNameLength;
WORD   FileNameOffset;
WCHAR FileName\[1\];

} USN_RECORD_V3, *PUSN_RECORD_V3;

ypedef struct {
USN_RECORD_COMMON_HEADER Header;
FILE_ID_128 FileReferenceNumber;
FILE_ID_128 ParentFileReferenceNumber;
USN Usn;
DWORD Reason;
DWORD SourceInfo;
DWORD RemainingExtents;
WORD NumberOfExtents;
WORD ExtentSize;
USN_RECORD_EXTENT Extents[1];
} USN_RECORD_V4, *PUSN_RECORD_V4;
