Identifies a reference pointer.

[ref]

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 ); 
};
