_BDANODE_DESCRIPTOR structure

Description

The BDANODE_DESCRIPTOR structure describes a BDA node.

Members

`ulBdaNodeType`

The node type as the BDA template topology identifies it. The BDA node-type identifier typically corresponds to the index of the element in the zero-based array of node types. This array of node types is an array of KSNODE_DESCRIPTOR structures.

`guidFunction`

GUID that describes the node's function. See BDA Node Category GUIDs for a list of these GUIDs.

`guidName`

GUID that can be used to store a string containing the name of the node. Applications can search the registry for this GUID to obtain the node's name and then can display the name.
