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

If you want to prohibit modification of a method parameter, then use the in attribute.

Пример

The following code shows a use of the readonly attribute:

// cpp_attr_ref_readonly.cpp
// compile with: /LD
[idl_quote("midl_pragma warning(disable:2461)")];
#include "unknwn.h"
[module(name="ATLFIRELib")];

[dispinterface, uuid(11111111-1111-1111-1111-111111111111)]
__interface IFireTabCtrl
{
   [readonly, id(1)] int i();
};
