3.1.4.2.91 ApiReAddNotifyNetwork (Opnum 91)

(Protocol Version 3) The ApiReAddNotifyNetwork method instructs the server to begin queuing event indications to the designated version 1 notification port. These indications, which correspond to internal cluster network state and configuration changes that map to a value in the designated filter, are queued for the resource object represented by the designated context handle.

The server MUST queue a separate event indication to the port for every filter that has the CLUSTER_CHANGE (section 2.2.2.7) value set that corresponds to the internal event.

The server MUST queue a CLUSTER_CHANGE_NETWORK_STATE event indication to the port if the StateSequence parameter is not equal to the internal state of the cluster network, as specified in section 3.1.4.2.83.

The server SHOULD accept an ApiReAddNotifyNetwork request if its protocol server state is read-only, and the server MUST accept the request for processing if it is in the read/write state, as specified in section 3.1.1.

 error_status_t ApiReAddNotifyNetwork(
   [in] HNOTIFY_RPC hNotify,
   [in] HNETWORK_RPC hNetwork,
   [in] DWORD dwFilter,
   [in] DWORD dwNotifyKey,
   [in] DWORD StateSequence,
   [out] error_status_t *rpc_status
 );

hNotify: A pointer to an HNOTIFY_RPC (section 2.2.1.6) context handle that was obtained in a previous ApiCreateNotify (section 3.1.4.2.56) method call.

hNetwork: A pointer to an HNETWORK_RPC (section 2.2.1.7) context handle that was obtained in a previous ApiOpenNetwork (section 3.1.4.2.81) or ApiOpenNetworkEx (section 3.1.4.2.120) method call.

dwFilter: A 32-bit integer containing one or more cluster network-specific values in a CLUSTER_CHANGE (section 2.2.2.7) enumeration. The value of this parameter MUST be set to the bitwise OR operator of one or more of the following values: CLUSTER_CHANGE_NETWORK_ADD, CLUSTER_CHANGE_NETWORK_DELETE, CLUSTER_CHANGE_NETWORK_STATE, or CLUSTER_CHANGE_NETWORK_PROPERTY.

dwNotifyKey: A 32-bit integer context value chosen by the client. This value MUST be returned to the client via a subsequent completion of the ApiGetNotify (section 3.1.4.2.66) method, if the name of the object pertaining to the event matches the name of the object designated by hNetwork (the second parameter).

dwStateSequence: A 32-bit integer value that was obtained from a call to ApiAddNotifyNetwork (section 3.1.4.2.90) or the most recent value obtained from subsequent calls to ApiGetNotify (section 3.1.4.2.66).

rpc_status: A 32-bit integer used to indicate success or failure. The RPC runtime MUST indicate, by writing to this parameter, whether the runtime succeeded in executing this method on the server. The encoding of the value passed in this parameter MUST conform to encoding for comm_status and fault_status, as specified in Appendix E of [C706].

Return Values: The method MUST return the following error codes for the specified conditions.

Return value/code

Description

0x00000000

ERROR_SUCCESS

Success.

0x00000006

ERROR_INVALID_HANDLE

The data that is pointed to by the hNotify parameter or the hNetwork parameter does not respectively represent a valid HNOTIFY_RPC (section 2.2.1.6) or HNETWORK_RPC (section 2.2.1.7) context handle.

For any other condition, this method MUST return a value that is not one of the values listed in the preceding table. The client MUST behave in one consistent, identical manner for all values that are not listed in the preceding table. The client SHOULD treat errors specified in section 3.2.4.6 as recoverable errors and initiate the reconnect procedure as specified in section 3.2.4.6.
