关于matlab 股票数据接口的编译问题-经管之家官网！

程序如下，但是用matlab mex编译 出错。求大侠帮忙。我用的版本是2010b的
void mexFunction(int nlhs,
mxArray * plhs[] , int nrhs,const mxArray * pahs[])

DWORD dt;//日期: 比如读出数据为20031110,代表2003年11月10号
DWORD k_price;//开盘价*0.01（）:读出的价格乘0.01为实际价格。下同。
DWORD h_price;//最高价*0.01
DWORD l_price;//最底价*0.01
DWORD s_price;//收盘价
float s_tolmoney;//(单位:亿)
DWORD bur_tol;//成交量
DWORD unknown; ///没有使用
