Specifying a Filter BLOB

When you select a registered network interface card (NIC) listed on a local computer, you can use a filter BLOB to disregard the NICs you are not interested in. For example, you could restrict the search for a specific type of card (such as ETHERNET) or a specific MAC address.

During the search for a NIC, every entry in the filter BLOB must match an equivalent entry in the NPP BLOB that represents the NIC. Filter BLOBs can also be special BLOBs.

When the GetNPPBlobFromUI function is called, the filter BLOB restricts the NICs displayed in the Select a network dialog box. When the GetNPPBlobTable function is called, the filter BLOB restricts the NICs returned in the BLOB table.

To use the filter, you must create a filter BLOB, set the values of the properties you want to filter on (including any special BLOB entries), and then specify the BLOB filter and a call to the GetNPPBlobTable or GetNPPBlobFromUI function.
