Visual C++通信编程工程实例精解(附盘)

static UINT SmsThread(LPVOID lpParam);  ／／短消息收发处理子线程
)；
编辑CSmsTraffic类的构造函数和析构函数，用于实现进程、消息队列的打开和关闭。
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);
 }
瀑加短消息与收发队列相关操作的函数。具体代码如下：
／，发出关闭子线程的信号
，／等待子线程关闭
／／将一条短消息放入发送队列
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);
)
，／从发送队列中取一条短消息
BOOL CSmsTraffic::GetSendMessage(SM_PARAM* pparam)
{
    BOOL fSuccess= FALSE;
    EnterCnticalSection(&m_csSend);
