100.dll调用

  • 在dll中声明 
    1 _declspec(dllexport) int a = 10;
    1 _declspec(dllexport)void go()
2 {
3     
4     MessageBoxA(0, "go", "go", 0);
5 
6 }

     

  • 调用dll 
    1 HINSTANCE hlib = LoadLibrary("DLL.dll");

     

  • 获取 
     1 if (hlib!=NULL)
 2     {
 3     
 4         p = (void(*)())GetProcAddress(hlib, "go");//获取地址，强制转换
 5         if (p!=NULL)
 6         {
 7             p();
 8         }
 9 
10     }

     

  • 释放 
    1 FreeLibrary(hlib);
