Note NDIS 5. x has been deprecated and is superseded by NDIS 6. x. For new NDIS driver development, see Network Drivers Starting with Windows Vista. For information about porting NDIS 5. x drivers to NDIS 6. x, see Porting NDIS 5.x Drivers to NDIS 6.0.

The MiniportCoDeleteVc function is required for connection-oriented miniports. MiniportCoDeleteVc indicates that a VC is being torn down and deleted by NDIS.

Syntax

NDIS_STATUS MiniportCoDeleteVc(
  _In_ NDIS_HANDLE MiniportVcContext
);

Parameters

MiniportVcContext [in]
Specifies the handle to a miniport driver-allocated context area in which the miniport driver maintains its per-VC state. The miniport driver supplied this handle to NDIS from its MiniportCoCreateVc function.

Return value

Return code	Description
NDIS_STATUS_SUCCESS	Indicates that the miniport driver successfully freed all resources allocated for this VC.

Remarks

MiniportCoDeleteVc must be written as a synchronous function and cannot, under any circumstances, return NDIS_STATUS_PENDING without causing a system-wide failure.

MiniportCoDeleteVc frees any resources allocated on a per-VC basis and stored in the context area MiniportVcContext. The miniport driver must also free the MiniportVcContext that is allocated in its MiniportCoCreateVc function.

Requirements

Target platform	Desktop
Version	See MiniportCoDeleteVc.
Header	Ndis.h (include Ndis.h)
IRQL	<= DISPATCH_LEVEL
