odl

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]

Remarks

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

Example

// 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(){}
};
