pb调用一个VC写的DLL（hestock.dll）时,该怎样申明和调用这个函数？
hestock.dll中有接口函数
int WINAPI GetStockByCodeEx(char * pszStockCode,int nMarket,RCV_REPORT_STRUCTEx * pBuf);
说明：
入口参数:
// pszStockCode 代号
// nMarket 市场
// pBuf 缓冲区
// 返回参数:
// NoStockData 无数据
其中：
typedef struct tagRCV_REPORT_STRUCTEx
{
WORD m_cbSize; time_t m_time;
WORD m_wMarket; char m_szLabel[STKLABEL_LEN];
char m_szName[STKNAME_LEN]; float m_fLastClose;
float m_fOpen; float m_fHigh;
float m_fLow;
float m_fNewPrice;
float m_fVolume;
float m_fAmount;
float m_fBuyPrice[3];
float m_fBuyVolume[3];
float m_fSellPrice[3];
float m_fSellVolume[3];
float m_fBuyPrice4;
float m_fBuyVolume4;
float m_fSellPrice4;
float m_fSellVolume4;
float m_fBuyPrice5;
float m_fBuyVolume5;
float m_fSellPrice5;
float m_fSellVolume5;
} RCV_REPORT_STRUCTEx, *PRCV_REPORT_STRUCTEx;
我改该怎样申明和调用这个函数？

这个问题 我给你看看
举个例子
Function string GetIp() library "IP.dll"
FUNCTION boolean SetCurrentDirectoryA(ref string cdir) LIBRARY "kernel32.dll"
FUNCTION ulong GetCurrentDirectoryA(ulong BufferLen, ref string currentdir) LIBRARY "Kernel32.dll"

//中英文输入法切换
function boolean ImmSimulateHotKey (UnsignedLong hWnd,UnsignedLong dwHotKeyID) library "IMM32.dll"
function unsignedlong GetKeyboardLayout (unsignedlong wLayout)library "user32.dll"
function boolean ImmIsIME (unsignedLong hklKeyboardLayout) library "IMM32.DLL"
