The BdaPropertyNodeEvents function retrieves a list of events that a node supports.
Points to the IRP for the request to retrieve the list of events for a node. The BDA minidriver receives this IRP with the KSPROPERTY_BDA_NODE_EVENTS request.
Points to a KSPROPERTY structure that describes the property and request type of the property request.
Points to an array that receives the list of GUIDs for the events supported by a node.
Returns STATUS_SUCCESS or an appropriate error code.
A BDA minidriver calls the BdaPropertyNodeEvents function to retrieve the list of events for a node after the minidriver receives a KSPROPERTY_BDA_NODE_EVENTS request of the KSPROPSETID_BdaTopology property set from the network provider. Most BDA minidrivers can define dispatch and filter-automation tables so that those minidrivers dispatch the BdaPropertyNodeEvents function directly, without intercepting this request using an internal get-handler (KStrGetPropertyHandler). See Defining Automation Tables and Determining BDA Device Topology for more information.
