Send Feedback

In the process of developing your NDIS miniport driver, you must implement the NDIS miniport driver functions.

These functions are either required for implementation or optional. The NDIS_MINIPORT_CHARACTERISTICS structure contains function pointers to the required and optional NDIS miniport driver functions.

Microsoft recommends replacing the Miniport prefix with a prefix that describes your network adapter.

The following table shows the NDIS miniport driver functions to implement and indicates whether they are required or optional.
