Compiler Error C2810 (Windows CE 5.0)
'interface' : an interface can only inherit from another interface
An interface may only inherit from another interface and may not inherit from a class or struct.
For example, the following code generates a C2810 error:
// compile with /cl /c
#include <unknwn.h>
#undef interface
#pragma keyword("interface", on)
class CBase1 {
public:
HRESULT mf1();
int m_i;
};
[com, uuid="40719E20-EF37-11D1-978D-0000F805D73B"]
interface IDerived : public CBase1 { // 2810 : cannot inherit from a class
HRESULT mf2(void *a);
};
struct CBase2 {
HRESULT mf1(int a, char *b);
HRESULT mf2();
};
[com, uuid="50719E20-EF37-11D1-978D-0000F805D73B"]
interface IDerived2 : public CBase2 { // 2810 : cannot inherit from a struct
HRESULT mf3(double a);
};
