[問題] python ctypes調用dll問題

[waynezen (Wayne)]

各位先進大家好
小弟非資工本科出生，最近因為工作需要接觸到了python這個語言，都還在自學階段
還請各位指教

使用ctypes調用一組dll庫，設備是一組RFID卡機


protocol
---------------------------------------------------
Prototype: int WINAPI rf_request (unsigned short icdev,
                                  unsigned char model,
                                  unsigned short *pTagType)

Parameter: icdev:  [IN] Device ID
           model:  [IN] REQ MODE
           pTagType: [OUT] response data, chip type code

Return 0 on success

Annotation: mode = 0x26: REQ_STD
            mode = 0x52: REQ_ALL
----------------------------------------------------



import ctypes

dll = ctypes.windll.LoadLibrary("MasterRD.dll")

request = dll.rf_request(0,0x52,'TagType')

print request


回傳是0，代表有讀取成功

但我要如何調到機器的回應值TagType??


感謝各位
