ClusterNodeOpenEnum function (clusapi.h)

Opens an enumerator for iterating through the network interfaces
or groups installed on a node. The PCLUSAPI_CLUSTER_NODE_OPEN_ENUM type defines a pointer to this function.

Syntax

HNODEENUM ClusterNodeOpenEnum(
  [in] HNODE hNode,
  [in] DWORD dwType
);

Parameters

[in] hNode

Handle to a node.

[in] dwType

Bitmask describing the type of objects to be enumerated. The following values of the CLUSTER_NODE_ENUM enumeration are valid.

CLUSTER_NODE_ENUM_NETINTERFACES (0x00000001)

Enumerate the network interface objects on the node.

CLUSTER_NODE_ENUM_GROUPS (0x00000002)

Enumerate the cluster groups on the node.

CLUSTER_NODE_ENUM_ALL ((CLUSTER_NODE_ENUM_NETINTERFACES | CLUSTER_NODE_ENUM_GROUPS))

Enumerate the network interfaces objects and cluster groups on the node.

Windows Server 2008:  The CLUSTER_NODE_ENUM_GROUPS value is not supported before Windows Server 2008 R2.

Return value

If the operation succeeds, ClusterNodeOpenEnum returns a handle to a node enumerator.

If the operation fails, the function returns NULL. For more information about the error, call the GetLastError function.

Remarks

The ClusterNodeOpenEnum function returns a handle that can be passed to ClusterNodeEnum to access each of the objects to be enumerated and to ClusterNodeCloseEnum to release the enumerator.
