编写ocx插件，写了一个简单的初始化串口的例子，遇到了问题，请教下

[T-Mac-Paul]

typedef SHORT (*_icInit)(SHORT, LONG);
SHORT CMFCActiveXControl1Ctrl::icInit(SHORT port, LONG baud)
{
	AFX_MANAGE_STATE(AfxGetStaticModuleState());

	// TODO: 在此处添加分派处理程序代码
	HINSTANCE hDLL = NULL;
	SHORT outstr = -1;
	_icInit SigIn;
	hDLL = LoadLibrary(TEXT("D:\\Mwic_32.dll"));
	if (hDLL != NULL)
	{
		_icInit SigIn = (_icInit)GetProcAddress(hDLL, "ic_init");
		outstr = SigIn(0, 9600);
	}
	FreeLibrary(hDLL);
	
	return outstr;
}

这里是源码，发生了异常，下图为异常报错


Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.

第一次写，有不足之处，还请指出

调用约定... 你声明的函数指针是默认的cdecl，它DLL中的函数很可能是stdcall

嗯，可以咨询这个组件的提供商，他们应该有接口说明
