This function ensures that data that has just transferred from a bus master network card and is about to be read from driver-allocated shared memory is current.

Syntax

VOID NdisMUpdateSharedMemory(
  NDIS_HANDLE MiniportAdapterHandle,
  ULONG Length,
  PVOID VirtualAddress,
  NDIS_PHYSICAL_ADDRESS PhysicalAddress
);

Parameters

• MiniportAdapterHandle
  [in] Handle originally input to the MiniportInitialize function.

• Length
  [in] Specifies the number of bytes in the range.
