This interface is the base class used for performing overlapped operations.
The INDOverlapped interface inherits from the IUnknown interface. INDOverlapped also defines the following types of members:
The INDOverlapped interface defines the following methods.
Cancels any in-progress overlapped requests.
Retrieves the result of an overlapped request.
Many operations in the Network Direct service provider interface (SPI) take an OVERLAPPED structure as input. These operations provide the same functionality as Win32 asynchronous I/O operations. For added flexibility, the class also exposes the adapter's underlying file handle on which asynchronous operations are performed.
Providers never invoke callbacks into client code; all notifications are explicitly requested by the client.
