急问：在驱动中间创建一个文件夹总是返回NT_STATUS_OBJECT_NAME_INVALID

555,请教各位大侠，这俩天被驱动快搞疯了
相关代码如下：
OBJECT_ATTRIBUTES objectAttributes;
HANDLE hFile;
IO_STATUS_BLOCK iostatus;
UNICODE_STRING DirectoryUnicodeString;
RtlInitUnicodeString(&DirectoryUnicodeString,L"\\??\\F:\\download_recv\\");
InitializeObjectAttributes(&objectAttributes,&DirectoryUnicodeString,OBJ_CASE_INSENSITIVE|OBJ_KERNEL_HANDLE,NULL,NULL);
status = ZwCreateFile(&hFile,
GENERIC_WRITE|GENERIC_READ,
&objectAttributes,
&iostatus,
NULL,
FILE_ATTRIBUTE_NORMAL,
FILE_SHARE_READ|FILE_SHARE_WRITE,
FILE_OVERWRITE_IF,
FILE_DIRECTORY_FILE,
NULL,
0);

问题已解决：是ZwCreateFile参数的问题
