本文介绍了一个基于C++的多线程网络应用程序实例，该程序通过创建多个线程来处理客户端连接请求，每个线程负责一个客户端的通信工作。文章展示了.h和.cpp文件中的关键代码段，包括线程的启动、运行及关闭过程。

一，C++

//.h文件/////////////

HANDLE thread_Socket[50]; //线程个数

DWORD WINAPI ServerPreDeal(LPVOID lpParameter);

struct MassageToStruct
{
CdwcjtestDlg *cStcmylog;
int ConnectID;
MassageToStruct()
{
cStcmylog = NULL;
ConnectID=0;
}
}readcom[64];

-------------------------------------------------------------------

/////.CPP文件///////

//启动

unsigned long id;
int ConnectID;
ConnectID= 0;
memset(readcom,0,sizeof(MassageToStruct));
for(int i = 0 ; i <g_ThreadNum; i ++ )
{
  ConnectID = i;
  //if(thread_Socket[ConnectID] == NULL)
  {
   readcom[ConnectID].ConnectID = ConnectID+1;
   readcom[ConnectID].cStcmylog = this;
   thread_Socket[ConnectID]=CreateThread(NULL, 0, ServerPreDeal,(LPVOID)&readcom[ConnectID], 0, &id);
   if (thread_Socket[ConnectID] == NULL)
   {
    memset(cReadBuff,0,sizeof(cReadBuff));
    sprintf(cReadBuff,"线程%d启动失败！",ConnectID);
    log(cReadBuff,1,ConnectID);
    return;
   }
  }
}

DWORD WINAPI ServerPreDeal(LPVOID lpParameter)
{
MassageToStruct stmassage;
memset(&stmassage,0,sizeof(MassageToStruct));
stmassage.cStcmylog = ((MassageToStruct*)lpParameter)->cStcmylog;
stmassage.ConnectID =((MassageToStruct*)lpParameter)->ConnectID;
char prbuff[256];
memset(prbuff,0,sizeof(prbuff));
sprintf(prbuff,"%s%d%s","接受线程",stmassage.ConnectID,"启动");
stmassage.cStcmylog->log(prbuff,1,stmassage.ConnectID+1);

while(1)
{
  memset(prbuff,0,sizeof(prbuff));
  sprintf(prbuff,"%s%d%s","线程",stmassage.ConnectID,"执行");
  stmassage.cStcmylog->log(prbuff,1,stmassage.ConnectID+1);
  Sleep(3000);
}//end wile
free(lpParameter);
}

//关闭线程///

DWORD ExitCode;
for(int ConnectID=0;ConnectID < g_ThreadNum;ConnectID++)
{
  GetExitCodeThread(thread_Socket[ConnectID],&ExitCode);
  TerminateThread(thread_Socket[ConnectID],ExitCode);
  thread_Socket[ConnectID]=NULL;
}
