Which is to say:

import ctypes

class IP2LocationRecord(ctypes.Structure):
	_fields_ = [
		('country_short', ctypes.c_char_p),
		('country_long', ctypes.c_char_p),
		('region', ctypes.c_char_p),
		('city', ctypes.c_char_p),
		('isp', ctypes.c_char_p),
		('latitude', ctypes.c_float),
		('longitude', ctypes.c_float),
		('domain', ctypes.c_char_p),
		('zipcode', ctypes.c_char_p),
		('timezone', ctypes.c_char_p),
		('netspeed', ctypes.c_char_p),
   	]

IP2LocationRecord_Ptr_t = ctypes.POINTER(IP2LocationRecord)

function.restype = IP2LocationRecord_Ptr_t
