在Python中调用GetLogicalProcessorInformation()函数可以通过使用ctypes库来实现。ctypes是Python的一个外部库,用于调用C函数库中的函数。
以下是在Python中调用GetLogicalProcessorInformation()函数的步骤:
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.")
get_logical_processor_information()
这样就可以在Python中调用GetLogicalProcessorInformation()函数并获取系统的逻辑处理器信息。请注意,此方法仅适用于Windows操作系统。
