1. THE HANDLE DEFINITION:

     typedef LONG HRESULT;
     typedef int HFILE;
     typedef DWORD HREFTYPE;


2. REFERENCE CODE:

     In x64, usually, the HANDLE is QWORD, except HRESULT, HFILE and HREFTYPE, they remain DWORD.

     I have found some code such as:
     ; HREFTYPE = eax
     mov dword ptr [rbx] , eax

     So HREFTYPE is a DWORD.
