Abstract
A component, such as a Component Object Model (COM) object, operates as an intermediary between an Application Programming Interface (API) extension or plug-in and a driver. The component allows additional objects to be aggregated onto the component, and/or sets one or more setting values for a received request so that an I/O call associated with the request can be completed in a manner that is compatible with other I/O calls. The component may also return, in response to a particular request, a stream index associated with the component.
