  • VirtualAddress
    [in] Pointer to the base virtual address of the allocated memory. This address was returned by the NdisAllocateMemory function.

  • MemoryFlags
    [in] Specifies 0 or the bitmask originally passed to NdisAllocateMemory for the preceding range. The following table shows valid memory flag values.

    Value Description
