步骤1: 编写 C 代码 首先,我们需要编写一个简单的 C 代码,并将其编译成 DLL。以下是一个简单的 C 示例,其中包含一个可以被 Python 调用的函数: // example.c#include<stdio.h>// 定义一个函数指针类型typedefvoid(*CallbackFn)(int);// 一个简单的 C 函数,接受一个函数指针作为参数__declspec(dllexport...
Api5040S_NameSpace.Api5040S CallDll = new Api5040S_NameSpace.Api5040S(); string strErr = ""; float fPower = -45; int iPort = Convert.ToInt32(1); Console.Write(CallDll.fnGetPowerValue(1, "192.168.100.3", ref strErr, ref fPower, 2437, "192.168.100.254")); Console.Write(fPowe...
ll = ctypes.cdll.LoadLibrary lib = ll("./libpycall.so") lib.foo(1, 3) print '***finish***' 运行方法: gcc -o libpycall.so -shared -fPIC pycall.c python pycall.py 第2种、Python调用C++(类)动态链接库(利用ctypes) pycallclass.cpp 1 2 3 4 5 6 7 8 9 10 11 12 13 ...
生成libpycallcpp.so,在Python中调用。Python文件:py_call_c.py import ctypes dll = ctypes.cdll.LoadLibrary lib = dll('./libpycallcpp.so') //刚刚生成的库文件的路径 lib.display() lib.display_int(0) 输出为: First display Second display:0 ...
python 调用c++ dll 动态库 一丶C++ 编译类动态库 1)新建生成.dll文件的空项目 双击: 2)编写头文件:pycall.h //test.h#pragma onceclass Mymath {intsum(int,int);intsub(int,int); }; 1 2 3 4 5 6 7 注:#define DLLEXPORT extern “C” __declspec(dllexport) ...
3.Python调用动态库的文件：pycallclass.py importctypesso=ctypes.cdll.LoadLibrarylib=so("./libpy...
使用CDLL那个最简单的方式调用 Traceback(most recent call last):File".\cmp.py",line45,in<module>lib=ctypes.CDLL('cdecl_sum.dll')File"C:\ProgramData\Anaconda3\lib\ctypes\__init__.py",line344,in__init__self._handle=_dlopen(self._name,mode)OSError:[WinError193]%1不是有效的Win32应用程...
