GetClusterFromNetInterface function (clusapi.h)

Returns a handle to the cluster associated with a network interface. The PCLUSAPI_GET_CLUSTER_FROM_NET_INTERFACE type defines a pointer to this function.

Syntax

HCLUSTER GetClusterFromNetInterface(
  [in] HNETINTERFACE hNetInterface
);

Parameters

[in] hNetInterface

Handle to the network interface.

Return value

If the operation succeeds, the function returns a handle to the cluster that owns the network interface.

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

Remarks

For hNetInterface to be a valid handle, there must necessarily be an open cluster handle (see OpenClusterNetInterface). GetClusterFromNetInterface returns another instance of the handle from which hNetInterface was obtained.

Be sure to call CloseCluster on the handle returned from GetClusterFromNetInterface before the handle goes out of scope. Closing this handle does not invalidate hNetInterface or the cluster handle from which hNetInterface was obtained.
