我在c中編寫了一個(gè)dll庫(kù)，使用vs2017 64位編譯，并嘗試使用64位python3.6加載它。但是，對(duì)象的成員變量的地址被截?cái)酁?2位。這是我的sim.c文件，它被編譯為sim.dll：class Detector {public:    Detector();    void process(int* pin, int* pout, int n);private:    int member_var;};Detector::Detector(){    memset(&member_var, 0, sizeof(member_var));    myfile.open("addr_debug.txt");    myfile << "member_var init address: " << &member_var << endl;}void Detector::process(int* pin, int* pout, int n);{    myfile << "member_var process address: " << &member_var << endl;    myfile.close();}#define DllExport   __declspec( dllexport )  extern "C" {    DllExport Detector* Detector_new() { return new Detector(); }    DllExport void Detector_process(Detector* det, int* pin, int* pout, int n)    {        det->process(pin, pout, n);    }}這是我的python腳本：from ctypes import cdlllib = cdll.LoadLibrary(r'sim.dll')class Detector(object):    def __init__(self):        self.obj = lib.Detector_new()    def process(self,pin, pout, n):        lib.Detector_process(self.obj,pin, pout, n)detector = Detector()n = 1024a = np.arange(n, dtype=np.uint32)b = np.zeros(n, dtype=np.int32)aptr = a.ctypes.data_as(ctypes.POINTER(ctypes.c_int))bptr = b.ctypes.data_as(ctypes.POINTER(ctypes.c_int))detector.process(aptr, bptr, n)這是addr_debug.txt中member_var的地址：member_var init address:    0000025259E123C4member_var process address: 0000000059E123C4因此訪問(wèn)它會(huì)觸發(fā)內(nèi)存訪問(wèn)錯(cuò)誤：OSError: exception: access violation reading 0000000059E123C4我試圖了解這個(gè)問(wèn)題的一些嘗試：將member_var定義為public而不是private，而不是幫助，地址仍然被截?cái)唷ember_var定義為全局變量，然后地址就可以了。所以我猜想在將對(duì)象返回到python或?qū)?duì)象傳遞回dll時(shí)會(huì)發(fā)生member_var地址截?cái)唷?
