// lib.cpp : 采用_stdcall修饰导出函数

BOOL APIENTRY DllMain( HANDLE hModule, 
					  DWORD  ul_reason_for_call, 
					  LPVOID lpReserved
					  )

	{

		break;
	case DLL_THREAD_DETACH:

//用任何一种方法输出函数时,确保用_stdcall调用约定, _stdcall 调用约定是用来调用Win32 API函数。
//_stdcall 以相反的顺序(从右到左) 把参数推入栈中
int _stdcall add(int x,int y)
{
	return x + y;
}
