C + + Build DLL method to invoke DLLs using Python _python

The first step is to build a CPP DLL project, and then write the following code to generate the DLL

Copy Code code as follows:

#include <stdio.h>

#define dllexport extern "C" __declspec (dllexport)

dllexport int __stdcall Hello ()
{
printf ("Hello world!\n");
return 0;
}

The second step is to write a python file:

Copy Code code as follows:

# Coding:utf-8

Import OS
Import cTYPES

Cur_path = Os.path.dirname (__file__)

if __name__ = = ' __main__ ':
print ' Starting ... '
DLL = cTYPES. Windll (Os.path.join (Cur_path, ' Hello.dll '))
Dll.hello ()
