'class': coclass does not implement a COM interface or pseudo-interface
A class marked with the coclass attribute did not implement an interface.
The following sample generates C4997:
// C4997.cpp
// compile with: /WX
// to resolve this C4997, uncomment all code
#include <objbase.h>
[ object ]
__interface I {
HRESULT func();
};
[ coclass ]
struct C /*: I*/ {
/*
HRESULT func() {
return S_OK;
}
*/
}; // C4997
