BdaPropertyNodeTypes function (bdasup.h)
The BdaPropertyNodeTypes function retrieves a list of node types in a template topology.
Syntax
NTSTATUS BdaPropertyNodeTypes(
[in] PIRP pIrp,
[in] PKSPROPERTY pKSProperty,
[out] ULONG *pulProperty
);
Parameters
[in] pIrp
Points to the IRP for the request to retrieve the list of node types. The BDA minidriver receives this IRP with the KSPROPERTY_BDA_NODE_TYPES request.
[in] pKSProperty
Points to a KSPROPERTY structure that describes the property and request type of the property request.
[out] pulProperty
Points to an array that receives the list of node types.
Return value
Returns STATUS_SUCCESS or an appropriate error code.
Remarks
A BDA minidriver calls the BdaPropertyNodeTypes function to retrieve the list of node types after the minidriver receives a KSPROPERTY_BDA_NODE_TYPES 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 BdaPropertyNodeTypes function directly, without intercepting this request using an internal get-handler (KStrGetPropertyHandler). See Defining Automation Tables and Determining BDA Device Topology for more information.
