借花献佛，给你贴上一个ReactOS的SetFileAttributesW实现。
- BOOL STDCALL
- SetFileAttributesW(LPCWSTR lpFileName,
- DWORD dwFileAttributes)
- {
- FILE_BASIC_INFORMATION FileInformation;
- OBJECT_ATTRIBUTES ObjectAttributes;
- IO_STATUS_BLOCK IoStatusBlock;
- UNICODE_STRING FileName;
- HANDLE FileHandle;
- NTSTATUS Status;
- DPRINT ("SetFileAttributeW(%S, 0x%lx) called\n", lpFileName, dwFileAttributes);
- /* Validate and translate the filename */
- if (!RtlDosPathNameToNtPathName_U (lpFileName,
- &FileName,
- NULL,
- NULL))
- {
- DPRINT ("Invalid path\n");
- SetLastError (ERROR_BAD_PATHNAME);
- return FALSE;
- }
- DPRINT ("FileName: \'%wZ\'\n", &FileName);
- /* build the object attributes */
- InitializeObjectAttributes (&ObjectAttributes,
- &FileName,
- OBJ_CASE_INSENSITIVE,
- NULL,
- NULL);
- /* Open the file */
- Status = NtOpenFile (&FileHandle,

- &ObjectAttributes,
- &IoStatusBlock,

- if (!NT_SUCCESS (Status))
- {
- DPRINT ("NtOpenFile() failed (Status %lx)\n", Status);
- SetLastErrorByStatus (Status);
- return FALSE;
- }
- Status = NtQueryInformationFile(FileHandle,
- &IoStatusBlock,
- &FileInformation,
- sizeof(FILE_BASIC_INFORMATION),

- if (!NT_SUCCESS(Status))
