Remarks
The nonextensible C++ attribute has the same functionality as the nonextensible MIDL attribute.
Use of nonextensible also requires the oleautomation attribute.
Example
The following code shows one use of the nonextensible attribute:
// cpp_attr_ref_nonextensible.cpp
// compile with: /LD
#include "unknwn.h"
[module(name="ATLFIRELib")];
[export] typedef long HRESULT;
[dual, nonextensible, ms_union, oleautomation,
uuid("00000000-0000-0000-0000-000000000001")]
__interface IFireTabCtrl
{
HRESULT procedure (int i);
};
