restricted

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
{
};
