IMFTopologyNode::GetTopoNodeID method (mfidl.h)
Retrieves the identifier of the node.
HRESULT GetTopoNodeID(
[out] TOPOID *pID
);
[out] pID
Receives the identifier.
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
When a node is first created, it is assigned an identifier. Node identifiers are unique within a topology, but can be reused across several topologies. The topology loader uses the identifier to look up nodes in the previous topology, so that it can reuse objects from the previous topology.
To find a node in a topology by its identifier, call IMFTopology::GetNodeByID.
