pass a struct to dictionary in pyx

[roman...@gmail.com]

Hi. I've been tortured by this problem for a long time.

This is a callback function provided by a dll. 

I will put this function in pyx file, and pyx is compiled by cython ,I could call it from python.

But the program crashed in function OnRtnOrder, Now I know it must be wrong  when I try to assign c++ struct member to a python dict.  

I don't know how to do. Please help.

cdef cppclass CUserSpi(CThostFtdcUserSpi):

void OnRtnOrder(CThostFtdcOrderField *pOrder):
        if not pOrder:
            return
        dictSpi = {}
        dictSpi['InvestorID'] = pOrder.InvestorID
        dictSpi['BrokerID'] = pOrder.BrokerID
        .........
        dictSpi['InstrumentID'] = pOrder.InstrumentID
        this.CallPythonPutQ(dictSpi)

 CThostFtdcOrderField is a struct, most of its members char arrays. It is defined in .h files.

struct CThostFtdcOrderField
{
 ///经纪公司代码
 TThostFtdcBrokerIDType BrokerID;
 ///投资者代码
 TThostFtdcInvestorIDType InvestorID;
 ///合约代码
 TThostFtdcInstrumentIDType InstrumentID;
 ///报单价格条件
 TThostFtdcOrderPriceTypeType OrderPriceType;
 ///买卖方向
 TThostFtdcDirectionType Direction;
 ///组合开平标志
 TThostFtdcCombOffsetFlagType CombOffsetFlag;
 ///组合投机套保标志
 TThostFtdcCombHedgeFlagType CombHedgeFlag;
 ///价格
 TThostFtdcPriceType LimitPrice;
 ///数量
 TThostFtdcVolumeType VolumeTotalOriginal;
 ///有效期类型
 TThostFtdcTimeConditionType TimeCondition;
 ///GTD日期
 TThostFtdcDateType GTDDate;
 ///最小成交量
 TThostFtdcVolumeType MinVolume;
 ///今成交数量
 TThostFtdcVolumeType VolumeTraded;
 ///剩余数量
 TThostFtdcVolumeType VolumeTotal;
 ///报单日期
 TThostFtdcDateType InsertDate;
 ///委托时间
 TThostFtdcTimeType InsertTime;
 ///IP地址
 TThostFtdcIPAddressType IPAddress;
 ///Mac地址
 TThostFtdcMacAddressType MacAddress;
};

the datatypes is like this:

typedef char TThostFtdcBrokerIDType[11];

typedef char TThostFtdcInvestorIDType[13];

typedef int TThostFtdcVolumeType;

typedef char TThostFtdcDateType[9];

typedef char TThostFtdcTimeType[9];

typedef double TThostFtdcPriceType;
