3.1.4.1.64 ApiReAddNotifyGroup (Opnum 63)

(Protocol Version 2) The ApiReAddNotifyGroup (section 3.1.4.1.64) method instructs the server to begin queuing event indications. Event indications correspond to internal clustergroup state and configuration changes that map to a value in the designated filter of the designated version 1 notification port. Indications are queued for the group 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 (section 2.2.2.7) that corresponds to the internal event.

The server MUST queue a CLUSTER_CHANGE_GROUP_STATE event indication to the port if the dwStateSequence parameter is not equal to the internal state sequence of the group.

The server SHOULD accept an ApiReAddNotifyGroup (section 3.1.4.1.64) request if its protocol server state is read-only and MUST accept the request for processing if it is in the read/write state, as specified in section 3.1.1.

error_status_t ApiReAddNotifyGroup(
  [in] HNOTIFY_RPC hNotify,
  [in] HGROUP_RPC hGroup,
  [in] DWORD dwFilter,
  [in] DWORD dwNotifyKey,
  [in] DWORD dwStateSequence
);

hNotify: A pointer to an HNOTIFY_RPC (section 2.2.1.6) context handle that was obtained in a previous ApiCreateNotify (section 3.1.4.1.56) method call.

hGroup: A pointer to an HGROUP_RPC (section 2.2.1.3) context handle that was obtained in a previous ApiOpenGroup (section 3.1.4.1.42) or ApiCreateGroup (section 3.1.4.1.43) method call.

dwFilter: A 32-bit integer containing one or more group-specific values in a CLUSTER_CHANGE enumeration. The value of this parameter MUST be set to the bitwise OR operator of one or more of the following values: CLUSTER_CHANGE_GROUP_ADD, CLUSTER_CHANGE_GROUP_DELETE, CLUSTER_CHANGE_GROUP_STATE, and CLUSTER_CHANGE_GROUP_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 3.1.4.1.66) method, if the name of the object pertaining to the event matches the name of the object designated by hGroup (the second parameter).

dwStateSequence: A 32-bit integer value that was obtained from a call to the ApiAddNotifyGroup (section 3.1.4.1.60) method, as specified in section 3.1.4.1.60, or from the most recent value obtained from subsequent calls to ApiGetNotify (section 3.1.4.1.66), as specified in section 3.1.4.1.66.

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 hGroup parameter does not respectively represent a valid HNOTIFY_RPC (section 2.2.1.6) or HGROUP_RPC (section 2.2.1.3) 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 3.2.4.6 as recoverable errors, and initiate the reconnect procedure as specified in section 3.2.4.6.
