attribute 'attribute' takes no arguments except on a coclass
Some attributes can be applied to more than one C++ construct, but arguments to the attribute may only be allowed on some constructs.
The following sample generates C3373:
#include <windows.h> [module(name="MyModule")]; [ object, uuid(373a1a4c-469b-11d3-a6b0-00c04f79ae8f) ] __interface IMyIface { // arguments to source and restricted are not allowed when // these attributes are applied to an interface [source(IMyIface)] HRESULT f1(); [restricted(IMyIface)] HRESULT f2(); }; [ coclass, uuid(373a1a4d-469b-11d3-a6b0-00c04f79ae8f) ] class CMyClass : public IMyIface { }; void main() { }
