Selecting a Network Interface Card

  • Artikkel

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.
