UINT
    EthNumberOfOpenFilterAddresses(
        IN PETH_FILTER  Filter,
        IN NDIS_HANDLE  NdisFilterHandle
        );

EthNumberOfOpenFilterAddresses is called by the NIC driver to count the number of Ethernet filter library database multicast addresses in a binding filter.

Parameters

Filter
Points to a previously created and initialized filter library database.
NdisFilterHandle
Specifies the handle that the filter library associates with the binding filter.

Return Value

EthNumberOfOpenFilterAddresses returns the number of multicast addresses in the binding filter.

Comments

A caller must be holding the database spin lock to call EthNumberOfOpenFilterAddresses, so the driver is running at IRQL DISPATCH_LEVEL.
