The IFWXExternalIOCompletion interface includes a method for receiving a notification from the Microsoft Firewall service upon completion of an asynchronous Windows input/output (I/O) operation involving reading or writing to a file on a disk for which the filter maintains a handle.
The IFWXExternalIOCompletion interface inherits the methods of the standard COM interface IUnknown.
In addition, IFWXExternalIOCompletion defines the following method.
