IHV-Specific Indications

  • Artículo

Important  The Native 802.11 Wireless LAN interface is deprecated in Windows 10 and later. Please use the WLAN Device Driver Interface (WDI) instead. For more information about WDI, see WLAN Universal Windows driver model.

 

The Native 802.11 miniport driver, operating in Extensible Station (ExtSTA) mode, can make IHV-specific indications to the Native 802.11 IHV Extensions DLL. The operating system forwards these indications to the DLL by calling the Dot11ExtIhvReceiveIndication IHV Handler function. If an IHV Extensions DLL is not installed, the operating system will discard the indication.

The Native 802.11 miniport driver makes an IHV-specific indication by calling the NdisMIndicateStatusEx function with the StatusCode member of the NDIS_STATUS_INDICATION structure set to NDIS_STATUS_MEDIA_SPECIFIC_INDICATION. The StatusBuffer member of this structure points to a driver-allocated buffer, which. contains data in a format that is defined by the IHV.
