VC++线程通信

这是我现在使用的一种线程通信方式的代码片段，两个线程之间通过自定义消息进行通知,

#defineMY_MSGWM_USER+100//线程通信的自定义消息
//消费者
DWORDConsumer::Run()
{//创建线程并启动
DWORDThreadId;
m_hThread=CreateThread(NULL,0,Routine,0,0,&ThreadId);//创建更新线程
if(NULL==m_hThread)
{
return-1;//启动失败
}

returnThreadId;//线程启动成功
}

DWORDWINAPIConsumer::Routine(LPVOIDlParam)
{//线程运行函数
std::cout<<"消费者线程启动/n";
MSGmsg;
PeekMessage(&msg,NULL,WM_USER,WM_USER,PM_NOREMOVE);

while(true)
{
if(GetMessage(&msg,0,0,0))//getmsgfrommessagequeue
{
switch(msg.message)
{
caseMY_MSG:
//dosomethinghere
std::cout<<"收到消息"<<std::endl;
break;
}
}
};
return0;
}
//生产者
DWORDProducer::Run(LPDEALFUNCTIONdealfun,LPVOIDlParam)
{
DWORDThreadId;
m_DealFun=dealfun;
m_DealFunParam=NULL;
m_hThread=CreateThread(NULL,0,Routine,this,0,&ThreadId);//创建监控线程
if(NULL==m_hThread)
{
return-1;
}
returnThreadId;
}

DWORDWINAPIProducer::Routine(LPVOIDlParam)
{
Producer&obj=*(Producer*)lParam;//生产者对象

while(!obj.m_bRequestStop)
{//线程就不断运行直到收到用户的退出请求
obj.m_DealFun(obj.m_DealFunParam);
}
return0;
}
//main.cpp
HANDLEhStartEvent;//threadstartevent
unsignednConsumerID,nProducerID;

void__stdcallMyDeal(LPVOIDlParam)
{
std::cout<<"开始发送消息.."<<std::endl;

if(!PostThreadMessage(nConsumerID,MY_MSG,NULL,NULL))//postthreadmsg
{
printf("postmessagefailed,errno:%d/n",::GetLastError());
}
::Sleep(1000);
}
intmain()
{
Consumerconsumer;
nConsumerID=consumer.Run();//启动更新线程

if(nConsumerID==-1)
{
std::cout<<"startthreadfailed"<<std::endl;
return-1;
}

ProducerpProducer;
nProducerID=pProducer.Run(&MyDeal,0);//启动监控线程
if(nProducerID==-1)
return-1;

return0;
}
