1. 编译如下c++代码时,不可在VS 2010的默认配置下进行编译,否则dll内部函数名会被更改;要么用cl.exe手动编译,要么在VS下的empty project下进行编译。 2. ctypes的cdll或者CDLL两种加载dll的模式下,加载后通过dir是找不到加载的dll内的函数名,但是可以直接调用。 3. ctypes带有c_char_p() 这种处理指针的函数。
一、Python调用C动态链接库 Python调用C库比较简单,不经过任何封装打包成so,再使用python的ctypes调用即可。 (1)C语言文件:pycall.c /***gcc -o libpycall.so -shared -fPIC pycall.c*/ #include <stdio.h> #include <stdlib.h> int foo(int a, int b) ...
Building a complete Python installation requires the use of various additional third-party libraries, depending on your build platform and configure options. Not all standard library modules are buildable or usable on all platforms. Refer to theInstall dependenciessection of theDeveloper Guidefor current...

Now that we’ve looked at library loading and function loading/calling, let’s take a look at how structure is implemented. Recall how you write a structure:highlight 複製 class VECTOR3(Structure): _fields_ = [("x", c_int), ("y", c_int), ("z"...
ctypes允许Python创建回调函数并将其传递给C函数。 from ctypes import CFUNCTYPE, c_int # 定义回调函数类型 callback_func = CFUNCTYPE(c_int, c_int, c_int) # 在C函数中使用Python回调函数 def my_callback(a, b): return a + b c_function_that_needs_callback = some_library.function_requiring_...
