NdiFindNdi

HNDI NdiFindNdi(ndiRelation, wNetClass, lpszDeviceId)
HNDI ndiRelation;    // NDI handle
WORD wNetClass;    // network class
LPCSTR lpszDeviceID;    // pointer to string

The NdiFindNDI procedure used for finding or enumerating the NDI objects in the system. For example, you can enumerate all drivers of a certain class, or look up a specific device ID.

ndiRelation

Identifies an NDI object. Pass NULL to search from all NDI objects. Pass in the return value from a previous call to NdiFindNdi to find the next object that matches your criteria.

wNetClass

Specifies the network object class to look for. If zero, all classes match.

Value	Meaning
NDI_CLASS_NET	Network adapter ("Net")
NDI_CLASS_TRANS	Network transport ("NetTrans")
NDI_CLASS_CLIENT	Network client ("NetClient")
NDI_CLASS_SERVICE	Network service ("NetService")

lpszDeviceID

Points to a buffer that contains the device ID to match. If NULL, all device IDs match.

The return value is the NDI handle that was found. If none was found, the return value is NULL.

Note that when searching for device IDs, more that one instance of that device ID may be installed, so you will want to call NdiFindNdi successively.
