GetClusterFromGroup function (clusapi.h)
Returns a handle to the cluster associated with a group. The PCLUSAPI_GET_CLUSTER_FROM_GROUP type defines a pointer to this function.
Syntax
HCLUSTER GetClusterFromGroup(
[in] HGROUP hGroup
);
Parameters
[in] hGroup
Handle to the group.
Return value
If the operation succeeds, the function returns a handle to the cluster that owns the group.
If the operation fails, the function returns NULL. For more information about the error, call GetLastError.
Remarks
For hGroup to be a valid handle, there must necessarily be an open cluster handle (see OpenClusterGroup). GetClusterFromGroup returns another instance of the handle from which hGroup was obtained.
Be sure to call CloseCluster on the handle returned from GetClusterFromGroup before the handle goes out of scope. Closing this handle does not invalidate hGroup or the cluster handle from which hGroup was obtained.
