[ros-dev] About GDIOBJHDR header changes

[Magnus Olsen]

what I reading the _ENTRY should look like this as final version, correct me 
if I am wrong

 typedef struct _ENTRY
{
    union
    {
        PDD_BASEOBJECT pobj;
        HANDLE hFree;
    } einfo;

    union
    {
         ULONG ulObj;
         struct
         {
                USHORT Count;
                USHORT Pid_Shifted;
         } Share;
    } ObjectOwner;
    USHORT FullUnique;
    UCHAR Objt;
    UCHAR Flags;
    PVOID pUser;
} DD_ENTRY, *PDD_ENTRY;
