NdisIMDeInitializeDeviceInstance (Compact 2013)

3/26/2014

This function calls an NDIS intermediate driver's MiniportHalt function to tear down the driver's virtual miniport.

Syntax

NDIS_STATUS 
  NdisIMDeInitializeDeviceInstance(
   NDIS_HANDLE NdisMiniportHandle
);

Parameters

• NdisMiniportHandle
  [in] The handle that NDIS supplied to the MiniportInitializeEx function.

Return Value

Value	Description
NDIS_STATUS_SUCCESS	If the network adapter has been torn down.
NDIS_STATUS_FAILURE	If the given NdisMiniportHandle is invalid.

Remarks

For NDIS intermediate drivers, NdisIMDeInitializeDeviceInstance is the reciprocal of NdisIMInitializeDeviceInstanceEx. Such a driver usually calls NdisIMDeInitializeDeviceInstanceEx from its ProtocolUnbindAdapter function, when the underlying network adapter to which it was bound is being removed from the system, possibly because it is being reconfigured.

The call to NdisIMDeInitializeDeviceInstance causes a call to the intermediate driver's MiniportHaltEx function after NDIS has told all higher-level protocols that had bound themselves to the intermediate's virtual network adapter that they must unbind.

Requirements

Header	ndis.h
Library	ndis.lib
