    FddiChangeFilterLongAddresses(
        IN PFDDI_FILTER  Filter,
        IN NDIS_HANDLE  NdisFilterHandle,
        IN PNDIS_REQUEST  NdisRequest,

        );

FddiChangeFilterLongAddresses is called by the NIC driver to attempt to change the multicast long address list for a binding filter in the FDDI filter library database.

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.

NdisRequest

Points to the request structure that this function passes to a NIC driver action function.

AddressCount

Specifies the number of elements to be added to the multicast long address list.

Addresses[][FDDI_LENGTH_OF_LONG_ADDRESS]

Specifies a two-dimensional character array to contain the new multicast long address list for the specified binding. FDDI_LENGTH_OF_LONG_ADDRESS is a constant specifying the length, in bytes, of an FDDI long address (defined in ffilter.h). The array is a sequence of 48-bit FDDI addresses (no padding between addresses).

Set

Specifies TRUE if changes do not result from the closing of a binding. This function does not use Set but passes it to a NIC driver action function.

Return Value

FddiChangeFilterLongAddresses can return the following status codes:

NDIS_STATUS_MULTICAST_FULL
NDIS_STATUS_PENDING
NDIS_STATUS_SUCCESS

Comments

If FddiChangeFilterLongAddresses does not change the filter long address list, it has no effect on this list or the multicast address list for the network interface card. If this function does change the filter long address list, it calls a NIC driver action function and waits for it to return. If the action function returns a status code that indicates neither pending nor success, FddiChangeFilterLongAddresses restores the filter library database to its original state.

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