Places an interface in the .idl file as a dispatch interface.

[dispinterface]

When the dispinterface C++ attribute precedes an interface, it causes the interface to be placed inside the library block in the generated .idl file.

Unless you specify a base class, a dispatch interface will derive from IDispatch. You must specify an id for the members of a dispatch interface.

The usage example for dispinterface in the MIDL documentation:

dispinterface helloPro
   { interface hello; };

is not valid for the dispinterface attribute.

See the example for bindable for an example of how to use dispinterface.
