What is the reference of objects in shared memory?

What is the reference of objects in shared memory? Delphi/Windows SDK/API
Http://www.delphi2007.net/DelphiAPI/html/delphi_20061201104623140.html
Type
Pshared = ^ tshared;
Tshared = record
Udpclient: tidudpclient;
Path: array [0 .. 255] of char;
SELF: integer;
Count: integer;
Hinst: integer;
End;

.....

Memfile: = createfilemapping ($ ffffffff, nil, page_readwrite, 0, sizeof (tshared), hookmemfilename );
Put the shared memory into all process spaces. Other processes cannot read udpclient, but the path can,
Because udpclient is an object,
I don't know where the problem is?

Follow

Udpclient: tidudpclient;
This is just a pointer and only occupies four bytes.

Therefore, objects cannot be used.

Only data can be shared between processes and objects cannot be shared.
