Rename Problem

NTFSD
1

In IRP_MJ_CLOSE complete routine, I call ZwCreateFile to open the file to be renamed, and call
ZwSetInformationFile to rename the file.
the second call is failure. the return satus is STATUS_INVALID_HANDLE. i can/t find the reason. I list the source below.
any help will be appreciate

InitializeObjectAttributes(&ObjectAttributes,
&FileName, //the name is a full path name
OBJ_CASE_INSENSITIVE,
NULL, NULL);
status = ZwCreateFile(
&hFile,
DELETE |GENERIC_READ | GENERIC_WRITE ,
&ObjectAttributes,
&IoStatusBlock,
NULL,
FILE_ATTRIBUTE_NORMAL,
0,
FILE_OPEN,
FILE_NON_DIRECTORY_FILE,
NULL,
0 );

//the target name is a full path name
RenameInfo.FileName[0] = RenameBuffer;
RenameInfo.FileNameLength = FileNameLength;
RenameInfo.ReplaceIfExists = TRUE;
RenameInfo.RootDirectory = NULL;
status = ZwSetInformationFile(
&hFile,
&IoStatusBlock,
&RenameInfo,
sizeof(RenameInfo),
FileRenameInformation);
i also try to open the target directory and ues the return handle to set the RenameInfo.RootDirectory. but the call to ZwSetInformationFile is still failure. return satus is the same.

Make sure FileNameLength does not include leading zeros. I had a problem
with that once.

Check your first parameter to ZwSetInformationFile(). You -really are- passing an invalid handle. ZwSetInformationFile() accepts a HANDLE, not a PHANDLE.
