static UINT SmsThread(LPVOID lpParam);  ／／短消息收發處理子線程
)；
編輯CSmsTraffic類的構造函數和析構函數，用于實現進程、消息隊列的打開和關閉。
CSmsTraffic::CSmsTraffic0
{
        m_nSendln = 0;
        m_nSendOut = 0;
        m_nRecvln = 0;
         m_nRecvOut = 0;
m_hKillThreadEvent = CreateEvent(NULL, TRUE, FALSE, NULL);
m_hThreadKilledEvent = CreateEvent(NULL, TRUE, FALSE, NULL);
InitializeCriticaISection(&m_csSend) ;
InitializeCriticalSection(&m_c sRecv);
AfxBeginThread(SmsThread, this, THREAD_PRIORITY_NORMAL);
CSmsTraffic::~CSmsTraffic0
 {
SetEvent(m_hKiIIThreadEvent);
                       WaitForSingleObj ect(m_hThreadKilledEvent,  INFINITE) ;
                       DeleteCriticalSection(&m_csS end);
                       DeleteCriticalSection(&m_csRecv) ;
CloseHandle(m_hKillThreadEvent);
CloseHandle(m_hThreadKilledEvent);
 }
瀑加短消息與收發隊列相關操作的函數。具體代碼如下：
／，發出關閉子線程的信號
，／等待子線程關閉
／／將一條短消息放入發送隊列
void CSmsTraffic::PutSendMessage(SM_PARAM* pparam)
{
    EnterCriticaISection(&m_csSend);
    memcpy(&m_SmSendlm_nSendln], pparam, sizeof(SM_PARAM》;
    m_nSendln++;
    if (m_nSendln>=MAX_SM_SEND)
    m_nSendln=0：
    LeaveCriticalSection(&m_csSend);
)
，／從發送隊列中取一條短消息
BOOL CSmsTraffic::GetSendMessage(SM_PARAM* pparam)
{
    BOOL fSuccess= FALSE;
    EnterCnticalSection(&m_csSend);
