ClusterResourceOpenEnum function (clusapi.h)
Opens an enumerator for iterating through a resource's dependencies and nodes. The PCLUSAPI_CLUSTER_RESOURCE_OPEN_ENUM type defines a pointer to this function.
Syntax
HRESENUM ClusterResourceOpenEnum(
[in] HRESOURCE hResource,
[in] DWORD dwType
);
Parameters
[in] hResource
A handle to a resource.
[in] dwType
A bitmask that describes the type of cluster objects to be enumerated.
The following values of the CLUSTER_RESOURCE_ENUM enumeration are valid.
CLUSTER_RESOURCE_ENUM_DEPENDS (1)
The object is a resource that the resource identified by the hResource parameter directly depends on.
CLUSTER_RESOURCE_ENUM_PROVIDES (2)
The object is a resource that depends on the resource identified by hResource.
CLUSTER_RESOURCE_ENUM_NODES (4)
The object is a node that can host the resource identified by hResource.
Return value
If the operation succeeds, the function returns an enumeration handle.
If the operation fails, the function returns NULL. For more information about the error, call the GetLastError function.
Remarks
Do not call ClusterResourceOpenEnum from any resource DLL entry point function. ClusterResourceOpenEnum can safely be called from a worker thread. For more information, see Function Calls to Avoid in Resource DLLs.
