Anmärkningar

Attribut kan inte tillämpas på malldefinitioner.

Example

I följande exempel genereras C3408.

// C3408.cpp
// compile with: /c
template <class T> struct PTS {
   enum {
      IsPointer = 0,
      IsPointerToDataMember = 0
   };
};

template <class T>
[coclass]   // C3408
struct PTS<T*> {
   enum {
      IsPointer = 1,
      IsPointerToDataMember = 0
   };
};

template
<class T, class U>
struct PTS<T U::*> {
   enum {
      IsPointer = 1,
      IsPointerToDataMember = 1
   };
};

struct S{};

extern "C" int printf(const char*,...);

int main() {
   S s, *pS;
   int S::*ptm;

   printf("PTS<S>::IsPointer == %d PTS<S>::IsPointerToDataMember == %d\n", PTS<S>::IsPointer, PTS<S>:: IsPointerToDataMember);
   printf("PTS<S*>::IsPointer == %d PTS<S*>::IsPointerToDataMember == %d\n", PTS<S*>::IsPointer, PTS<S*>:: IsPointerToDataMember);
   printf("PTS<int S::*>::IsPointer == %d PTS<int S::*>::IsPointerToDataMember == %d\n", PTS<int S::*>::IsPointer, PTS<int S::*>:: IsPointerToDataMember);
}
