ND_RESULT Structure
Provides the completion status of a request.
Syntax
typedef struct _ND_RESULT {
HRESULT Status;
SIZE_T BytesTransferred;
} ND_RESULT, *PND_RESULT;
Members
Status
Status of the request. See Remarks for the possible status values based on the type of operation.BytesTransferred
The number of bytes transferred by the request. Applies to Send, SendAndInvalidate, Receive, Read, and Write requests, and is undefined for other requests.
Remarks
The ND_RESULT structure that you pass to the Send, Receive, Read, Write, Bind, and Invalidate requests must remain valid for the duration of the request. (Even if the request returns ND_SUCCESS, you will still get a completion in the completion queue; you must ensure that the ND_RESULT you provided remains valid until the request completes in the completion queue.) The ND_RESULT structure that INDAdapter::CreateMemoryWindow returns is used to indicate when the peer invalidates the memory window.
The following table lists the possible status values.
| Status code | Description |
|---|---|
| ND_SUCCESS | The operation succeeded. |
| ND_LOCAL_LENGTH | The scatter/gather entries for a Send, Read, or Write request referenced more data than can be sent by the adapter. |
| ND_BUFFER_OVERFLOW | An incoming Send exceeded the buffer space referenced by a receive request. |
| ND_ACCESS_VIOLATION | The scatter/gather entries in a request referenced registered memory that is not valid, or a Bind operation attempted to bind to registered memory that is not valid. |
| ND_CANCELED | The request was canceled (generally due to a previous request failing). |
| ND_INVALID_REQUEST | The request was improperly formatted. |
| ND_FAILURE | The endpoint experienced an error while processing this request. |
| ND_TIMEOUT | The request timed out due to a connection failure or failure of the remote endpoint. |
| ND_REMOTE_ERROR | The request caused an error on the remote endpoint. |
| ND_INVALIDATION_ERROR | An Invalidate request or a SendAndInvalidate request attempted to invalidate a memory window that is not valid. |
The result is added to the completion queue when the request completes.
