Network Monitor provides three functions for selecting a network interface card (NIC). These functions provide three ways to enumerate a set of NICs and select the one you want to use. The following table lists these functions.
| Function | Description |
|---|---|
| GetNPPBlobFromUI | Uses the Network Monitor UI to display the registered NICs and returns the NPP BLOB that represents the NIC you are interested in. |
| GetNPPBlobTable | Returns a BLOB table. The application must enumerate the table and select an NPP BLOB. |
| SelectNPPBlobFromTable | Uses the Network Monitor interface to display the supplied NPP BLOBs and returns the NPP BLOB that represents the NIC you are interested in. |
Each NIC is represented by an NPP binary large object (BLOB). These functions can return a single NPP BLOB from those registered on the computer, a single NPP BLOB from a supplied NPP BLOB table, or a table of NPP BLOBs that the caller must then use to select a specific BLOB. In the first two cases, when selecting from the registered NICs or from a supplied NPP BLOB table, the Network Monitor UI displays the NICs you can select.
Note
Network Monitor uses a feature called the NPP Finder to enumerate the NICs registered on the local computer. The NPP Finder is a component of Npptools.dll.
