Example
// a user defined class derived from LInet should be used to support the OnDataStart callback function // suppose it was named as LUserInetODStart class LUserInetODStart : public LInet { protected: virtual L_INT OnDataStart(LInet plConnection, L_INT nError); }; L_INT LInet__OnDataStartExample() { L_INT nRet; LUserInetODStart UserInet; // connect to LEAD nRet = UserInet.Connect("207.238.49.190", 1000); if(nRet != SUCCESS) return nRet; return SUCCESS; } L_INT LUserInetODStart::OnDataStart(LInet plConnection, L_INT nError) { UNREFERENCED_PARAMETER(nError); // other operations return SUCCESS; }
