这不起作用:

class ifinfomsg(ctypes.Structure):

_fields_ = [

('ifi_family', ctypes.c_ubyte),

('__ifi_pad', ctypes.c_ubyte),

('ifi_type', ctypes.c_ushort),

('ifi_index', ctypes.c_int),

('ifi_flags', ctypes.c_uint),

('ifi_change', ctypes.c_uint(0xFFFFFFFF))

]

它错误:

File "rtnetlink.py", line 243, in

class ifinfomsg(ctypes.Structure):

TypeError: Error when calling the metaclass bases

second item in _fields_ tuple (index 5) must be a C type

但是我可以在__init __()中设置值:

class ifinfomsg(ctypes.Structure):

_fields_ = [

('ifi_family', ctypes.c_ubyte),

('__ifi_pad', ctypes.c_ubyte),

('ifi_type', ctypes.c_ushort),

('ifi_index', ctypes.c_int),

('ifi_flags',
