NDK_FN_DISCONNECT callback function

Description

The NdkDisconnect (NDK_FN_DISCONNECT) function starts a disconnect on an NDK connection.

Parameters

pNdkConnector [in]

A pointer to a connector object (NDK_CONNECTOR).

RequestCompletion [in]

A pointer to a request completion callback routine NdkRequestCompletion (NDK_FN_REQUEST_COMPLETION).

RequestContext [in, optional]

A context value to pass to the Context parameter of the callback function that is specified in the RequestCompletion parameter.

Return value

The NdkDisconnect function returns one of the following NTSTATUS codes.

Return code Description
STATUS_SUCCESS The disconnect request was completed successfully.
STATUS_PENDING The operation is pending and will be completed later. The driver will call the specified RequestCompletion (NDK_FN_REQUEST_COMPLETION) function to complete the pending operation.
STATUS_IO_TIMEOUT The disconnect handshake timed out.

Important The request can fail inline as well as asynchronously with this status code.
Other status codes An error occurred.

Remarks

NdkDisconnect initiates a graceful disconnect on a connection. After the underlying protocol driver performs a graceful disconnect, the NDK provider must also perform an implicit flush on the QP.
