c++ stl map 的问题！

xengine-qyt 2013-08-07 10:39:23

莫名其妙，搞不动啊，为什么客户端崩溃后在链接我我会挂掉？只要正常离开就没问题，刚开始我还以为是客户端离开后因为我收不到离开消息而导致重复KEY挂掉。。后来测试不是，怎么处理？
挂在STL INSERT 插入数据的时候，STL 挂了真不知道怎么调试。。太恼火了

链接代码:





    NetCore_IsErrorOccur = FALSE;



    struct sockaddr_in st_ClientAddr;

    socklen_t nLenAddr = sizeof(st_ClientAddr);

    NETCORE_TCPEPOLL_CLIENT st_EPollClient;

    TCHAR tszClientAddr[64];



    memset(tszClientAddr,'\0',64);

    memset(&st_ClientAddr,'\0',sizeof(st_ClientAddr));

    memset(&st_EPollClient,'\0',sizeof(st_EPollClient));



    SOCKET m_AccpetSocket = accept(hSocket,(struct sockaddr *)&st_ClientAddr,&nLenAddr);



    if (SOCKET_ERROR == m_AccpetSocket)

    {

        NetCore_IsErrorOccur = TRUE;

        NetCore_dwErrorCode = ERROR_NETENGINE_NETCORE_TCP_EPOLL_ACCEPT_ISFAILED;

        return FALSE;

    }



    if (!m_NetSocket.NetCore_Socket_SetNoneBlock(m_AccpetSocket))

    {

        return FALSE;

    }



    m_NetSocket.NetCore_Socket_KeepAlive(m_AccpetSocket);



    struct epoll_event st_ePollSocket;

    memset(&st_ePollSocket,'\0',sizeof(st_ePollSocket));



    if (bIsCtrl)

    {

        st_ePollSocket.events = EPOLLIN | EPOLLOUT | EPOLLET;

    }

    else

    {

        st_ePollSocket.events = EPOLLIN | EPOLLOUT | EPOLLET | EPOLLRDHUP | EPOLLERR;

    }

    st_ePollSocket.data.fd = m_AccpetSocket;

    if (bIsCtrl)

    {

        if (-1 == epoll_ctl(m_CtrlEPoll,EPOLL_CTL_ADD,m_AccpetSocket,&st_ePollSocket))

        {

            close(m_AccpetSocket);

            NetCore_IsErrorOccur = TRUE;

    pthread_mutex_init(&st_EPollClient.st_csWrite,NULL);

    pthread_mutex_lock(&st_EPollClient.st_csWrite);



    st_EPollClient.m_Socket = m_AccpetSocket;

    st_EPollClient.bIsCtrl = bIsCtrl;

    st_EPollClient.lParam = this;



    _stnprintf_s(tszClientAddr,sizeof(tszClientAddr),_T("%s:%d"),inet_ntoa(st_ClientAddr.sin_addr),ntohs(st_ClientAddr.sin_port));

    stl_MapClient.insert(make_pair(tszClientAddr,st_EPollClient));  //死在这里



    list<NETCORE_TCPEPOLL_SENDMSG> stl_ListSendMsg;

    stl_MapSendMsg.insert(make_pair(st_EPollClient.m_Socket,stl_ListSendMsg));



    map<tstring,NETCORE_TCPEPOLL_CLIENT>::iterator stl_MapIterator = stl_MapClient.find(tszClientAddr);

    pthread_mutex_unlock(&stl_MapIterator->second.st_csWrite);

    lpCall_ePoll_Login(tszClientAddr,bIsCtrl,m_lPLogin);

    return TRUE;
