STATUS_REPARSE don't work with method PREPARSE_DATA_BUFFER

[Sizy458]

Hello,
Then option '_shareconfig' is equal to 0 or 1 , it work good.
Why the method redirect by PREPARSE_DATA_BUFFER don't work ???
Thank.


PREPARSE_DATA_BUFFER PrepareBufferForRedirect(WCHAR *destmount, int mode)
{
PREPARSE_DATA_BUFFER Reparse=(PREPARSE_DATA_BUFFER)ExAllocatePoolWithTag(NonPagedPool, MAXIMUM_REPARSE_DATA_BUFFER_SIZE, 'FwrI');
if (Reparse != NULL)
{
USHORT _len = wcslen(destmount);
USHORT len = (_len+1) << 1;
RtlZeroMemory(Reparse, MAXIMUM_REPARSE_DATA_BUFFER_SIZE);
Reparse->ReparseTag = mode;
//int len = wcslen(destmount);

if (mode == IO_REPARSE_TAG_MOUNT_POINT)
{
Reparse->ReparseDataLength = 8+4 + len;//sizeof(L"\\??\\C:\\Documents and Settings");
Reparse->MountPointReparseBuffer.SubstituteNameLength = len - sizeof(UNICODE_NULL);
Reparse->MountPointReparseBuffer.PrintNameOffset = len;
RtlCopyMemory(Reparse->MountPointReparseBuffer.PathBuffer, destmount, len);
}
else
if (mode== IO_REPARSE_TAG_SYMLINK)
{
Reparse->ReparseDataLength = 12 + 4 + len;
Reparse->SymbolicLinkReparseBuffer.SubstituteNameLength = len - sizeof(UNICODE_NULL);
Reparse->SymbolicLinkReparseBuffer.PrintNameOffset = len;
RtlCopyMemory(Reparse->SymbolicLinkReparseBuffer.PathBuffer, destmount, len);
}
else
{
ExFreePool(Reparse);
Reparse = NULL;

}


}
return Reparse;
}
