Identifies a reference pointer.
Remarks
The ref C++ attribute has the same functionality as the ref MIDL attribute.
The following code shows how to use the ref attribute:
// cpp_attr_ref_ref.cpp
// compile with: /LD
#include <windows.h>
[module(name="ATLFIRELib")];
[dispinterface, uuid("00000000-0000-0000-0000-000000000001")]
__interface IFireTabCtrl
{
[id(1), unique] char * GetFirstName([in, ref] char * pszFullName );
};
