odl

The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

Identifies an interface as an Object Description Language (ODL) interface. The MIDL compiler does not require the odl attribute; it is recognized only for compatibility with older .odl files.

  
[odl]  
  

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

// cpp_attr_ref_odl.cpp  
// compile with: /LD  
#include <unknwn.h>  
[module(name="MyLIb")];  
  
[odl, oleautomation, dual, uuid("00000000-0000-0000-0000-000000000001")]  
__interface IMyInterface  
{  
   HRESULT x();  
};  
  
[coclass, uuid("00000000-0000-0000-0000-000000000002")]  
class cmyClass : public IMyInterface  
{  
public:  
   HRESULT x(){}  
};
