Compiler Error C3340

  • Artikkeli

'interface': interface cannot be both 'restricted' and 'default' in coclass 'class'

The restricted attribute and the default attribute are mutually exclusive.

The following sample generates C3340:

// C3340.cpp
#include <windows.h>
[module(name="MyModule")];

[ object, uuid(373a1a4c-469b-11d3-a6b0-00c04f79ae8f) ]
__interface IMyIface
{
   HRESULT f1();
};

[ coclass, uuid(373a1a4d-469b-11d3-a6b0-00c04f79ae8f),
default(IMyIface),
source(IMyIface),restricted(IMyIface) ]
class CmyClass // C3340
{
};

int main()
{
}
