刚知道aardio这个不错的玩具，可惜作者停更了，贴一个调用dll的例子备用吧

vc代码

extern "C" _declspec(dllexport) int _stdcall my_export(int a,int b)
{
return a + b;
}

def文件

LIBRARY "my_dll"

EXPORTS
my_export

aardio代码

mainForm.button.oncommand = function(id,event){
//后面默认是stdcall调用，写错会各种崩溃
dll = raw.loadDll("D:\projects\vc\my_dll\Debug\my_dll.dll");
/*
MyExportFunc = dll.api("my_export","int(int, int)");
result = MyExportFunc(1, 2);
*/
//函数可以直接调用
result = dll.my_export(,)
win.msgbox(tostring(result))
}
