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 x has been deprecated and is superseded by NDIS 6.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.

NdisMDeregisterInterrupt releases resources previously allocated with NdisMRegisterInterrupt.

Syntax

VOID NdisMDeregisterInterrupt(
  _In_ PNDIS_MINIPORT_INTERRUPT Interrupt
);

Parameters

Interrupt [in]
Pointer to an interrupt object previously registered with NdisMRegisterInterrupt.

Return value

None

Remarks

NdisMDeregisterInterrupt releases the association between the initialized interrupt object at Interrupt and the caller's MiniportISR function. After NdisMDeregisterInterrupt returns, NDIS will not call the miniport driver's MiniportISR function or MiniportHandleInterrupt function.

A miniport driver can call NdisMDeregisterInterrupt from its MiniportInitialize or MiniportHalt function only if MiniportInitialize previously made a successful call to NdisMRegisterInterrupt.

The miniport driver should disable its NIC from generating interrupts before it calls NdisMDeregisterInterrupt. After NdisMDeregisterInterrupt returns control, the miniport driver cannot call NdisMSynchronizeWithInterrupt.
