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.

Requirements

Product

 Microsoft Message Passing Interface (MS-MPI)
