User mode network link notification

NTDEV

Hi,

I know that if I pull a network cable from NIC, the little network icon will
immediately display network cable disconnect info. And if I plug the cable
back to NIC, the icon will display network cable connected. I wonder if
there is user mode API to receive such notification or do I have to pool
this info myself. The API has to be available for NT 4.0 if it exist.

Thanks.

Hi,

What I know is if there is user mode callback api that notify me if NDIS
miniport call NdisMIndicateStatus with
NDIS_STATUS_MEDIA_CONNECT/NDIS_STATUS_MEDIA_DISCONNECT without pooling or
writting Ndis IM or fake protocol driver.

Thanks.

User mode network link notificationNT4 has no such icons, and I expect that w2k’s thing uses either undocumented IOCTLs to NDIS.SYS or WMI.

User mode network link notificationThis information is available via the IPHLPAPI as MIB_IFROW.dwOperStatus. I don’t think one can be notified of a change, I think you must still use a polling technique -
