NdisMRegisterAdapterShutdownHandler

VOID
NdisMRegisterAdapterShutdownHandler(
IN NDIS_HANDLE MiniportHandle,
IN PVOID ShutdownContext,
IN ADAPTER_SHUTDOWN_HANDLER ShutdownHandler
);

NdisMRegisterAdapterShutdownHandler registers a NIC-driver-supplied MiniportShutdown function to be called when the system is shutting down.

Parameters

MiniportHandle: Specifies the handle input to MiniportInitialize.
ShutdownContext: Points to a driver-determined context area. This pointer will be passed to the function at ShutdownHandler when it is called.
ShutdownHandler: Specifies the entry point of the caller’s MiniportShutdown function.

Comments

Whenever a MiniportInitialize function successfully initializes a NIC, it calls NdisMRegisterAdapterShutdownHandler, usually just before MiniportInitialize returns NDIS_STATUS_SUCCESS.

Every NIC driver should register a MiniportShutdown function when it initializes. MiniportShutdown is responsible for restoring the NIC to its initial state before the system is shut down.

Callers of NdisMRegisterAdapterShutdownHandler run at IRQL PASSIVE_LEVEL.
