时间Sun May 24 14:09:02 2015
各位先进大家好
小弟非资工本科出生，最近因为工作需要接触到了python这个语言，都还在自学阶段
还请各位指教
使用ctypes调用一组dll库，设备是一组RFID卡机
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
回传是0，代表有读取成功
但我要如何调到机器的回应值TagType??
感谢各位
