Methods
The INDOverlapped interface defines the following methods.
| Method | Description |
|---|---|
| CancelOverlappedRequests | Cancels any in-progress overlapped requests. |
| GetOverlappedResult | Retrieves the result of an overlapped request. |
Remarks
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.
