int ns_del_filter (nddp, filter, len)
struct ndd *nddp;
caddr_t filter;
int len;
| nddp | Specifies the ndd structure that this delete request is for. |
| filter | Specifies the pointer to the receive filter. |
| len | Specifies the length in bytes of the receive filter. |
The ns_del_filter network service deletes the receive filter from the corresponding network demuxer. This disables packet reception for packets that match the filter. The delete request is passed on to the nd_del_filter function of the demuxer for the specified network device driver (NDD).
The following example illustrates the ns_del_filter network service:
struct ns_8022 dl; dl.filtertype = NS_LLC_DSAP_SNAP; dl.dsap = 0xaa; dl.orgcode[0] = 0x0; dl.orgcode[1] = 0x0; dl.orgcode[2] = 0x0; dl.ethertype = 0x0800; ns_del_filter(nddp, &dl, sizeof(dl));
| 0 | Indicates the operation was successful. |
The network demuxer may supply other return values.
The ns_add_filter network service, ns_alloc network service.
