[vararg]

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

The following code shows a use of vararg:

// cpp_attr_ref_vararg.cpp
// compile with: /LD
#include "unknwn.h"
#include "oaidl.h"
[module(name="MyLibrary")];

[object, uuid("00000000-0000-0000-0000-000000000001")]
__interface X : public IUnknown 
{
   [vararg] HRESULT Button([in, satype(VARIANT)]SAFEARRAY *psa);
};
