Try ZwCreateFile() with flag FILE_DIRECTORY_OBJECT

ZwCreateDirectoryObject() create directory not in FS. This is
directory for named objects (see winobj.exe from sysinternals)

thank you!
I tried with FILE_DIRECTORY_OBJECT but fail and i will try again.
and i have a question:
i use ZwWriteFile write a buffer to a disk and in win2000 it is normal,but in xp with sp1 it is false and the return status is 0xc0000022
the open operation is successful and write is false.
the code is following:
strcpy( tempfullPathName,“\??\D:\zxp.dat” );
//RtlInitAnsiString( &fileNameAnsiString,g_pPointer.filename );
RtlInitAnsiString( &fileNameAnsiString,tempfullPathName );
RtlAnsiStringToUnicodeString( &fileNameUnicodeString,&fileNameAnsiString,TRUE );
InitializeObjectAttributes( &objectAttributes, &fileNameUnicodeString,
OBJ_CASE_INSENSITIVE, NULL, NULL );
ntStatus = ZwCreateFile( &ntFileHandle, SYNCHRONIZE|FILE_ANY_ACCESS,
&objectAttributes, &ioStatus, NULL, 0,FILE_SHARE_WRITE,
FILE_OPEN,
FILE_NON_DIRECTORY_FILE |
FILE_RANDOM_ACCESS |
FILE_NO_INTERMEDIATE_BUFFERING |
FILE_SYNCHRONOUS_IO_NONALERT,
NULL, 0 );
if( !NT_SUCCESS( ntStatus ) ) {
DbgPrint((“IRP_MJ_WRITE— Could not open %s\n”, ntStatus ));
}
memset((char *)&OffSet,0,sizeof(LARGE_INTEGER));
DbgPrint((“Debug— Buffer %s %d \n”, g_pPointer.pBuffer,g_pPointer.dwLen ));
ntStatus = ZwWriteFile(ntFileHandle,
NULL,
NULL,
NULL,
&ioStatus,
tempBuffer,
strlen(tempBuffer),
&OffSet,
NULL
);
if( !NT_SUCCESS( ntStatus ) ) {
DbgPrint((“IRP_MJ_WRITE— Could not WRITE %s\n”, ntStatus ));
//return FALSE;
}

> i use ZwWriteFile write a buffer to a disk

and in win2000 it is normal,but in xp with
sp1 it is false and the return status is 0xc0000022
the open operation is successful and write is false.
the code is following:

Well, If I understand it well, the code is STATUS_ACCESS_DENIED.
Try to find why (my personal guess is that FILE_ANY_ACCESS
can not be used with ZwCreateFile.
