如何在Python中调用GetLogicalProcessorInformation()？

import ctypes

class SYSTEM_LOGICAL_PROCESSOR_INFORMATION(ctypes.Structure):
    _fields_ = [("ProcessorMask", ctypes.c_ulonglong),
                ("Relationship", ctypes.c_uint),
                ("Reserved", (ctypes.c_uint * 2)),
                ("ProcessorCore", ctypes.c_uint),
                ("NumaNode", ctypes.c_uint),
                ("Cache", ctypes.c_uint * 3)]

def get_logical_processor_information():
    # 加载kernel32.dll库
    kernel32 = ctypes.WinDLL('kernel32')
    
    # 定义GetLogicalProcessorInformation函数的参数类型
    kernel32.GetLogicalProcessorInformation.argtypes = [ctypes.POINTER(SYSTEM_LOGICAL_PROCESSOR_INFORMATION), ctypes.POINTER(ctypes.c_ulong)]
    
    # 获取系统信息
    buffer_size = ctypes.c_ulong(0)
    kernel32.GetLogicalProcessorInformation(None, ctypes.byref(buffer_size))
    
    # 分配内存
    buffer = (ctypes.c_byte * buffer_size.value)()
    
    # 调用GetLogicalProcessorInformation函数
    success = kernel32.GetLogicalProcessorInformation(ctypes.cast(buffer, ctypes.POINTER(SYSTEM_LOGICAL_PROCESSOR_INFORMATION)), ctypes.byref(buffer_size))
    
    if success:
        # 解析结果
        processor_info = (SYSTEM_LOGICAL_PROCESSOR_INFORMATION * (buffer_size.value // ctypes.sizeof(SYSTEM_LOGICAL_PROCESSOR_INFORMATION))).from_buffer(buffer)
        
        for info in processor_info:
            print("Processor Mask: 0x{:016X}".format(info.ProcessorMask))
            print("Relationship: {}".format(info.Relationship))
            print("Processor Core: {}".format(info.ProcessorCore))
            print("Numa Node: {}".format(info.NumaNode))
            print("Cache: L1={}, L2={}, L3={}".format(info.Cache[0], info.Cache[1], info.Cache[2]))
    else:
        print("Failed to get logical processor information.")
