Specifies that a member of a module, interface, or dispinterface cannot be called arbitrarily.

Syntax

  
      [ restricted(  
   interfaces  
) ]

Parameters

interfaces
One or more interfaces that may not be called arbitrarily on a COM object. This parameter is only valid when applied to a class.

Remarks

The restricted C++ attribute has the same functionality as the restricted MIDL attribute.

Example

The following code shows how to use the restricted attribute:

// cpp_attr_ref_restricted.cpp  
// compile with: /LD  
#include "windows.h"  
#include "unknwn.h"  
[module(name="MyLib")];  
  
[object, uuid("00000000-0000-0000-0000-000000000001")]  
__interface a  
{  
};  
  
[object, uuid("00000000-0000-0000-0000-000000000002")]  
__interface b  
{  
};  
  
[coclass, restricted(a,b), uuid("00000000-0000-0000-0000-000000000003")]  
class c : public a, public b  
{  
};
