在Main中

        TVQ_THREAD_CONTROL thread_ctf;
        
//New Thread        
        TVQ_Thread *listen_thread = new TVQ_Thread();
        //-----------------------------------------------
        TVQ_Thread *job_thread1 = new TVQ_Thread();        
        TVQ_Thread *job_thread2 = new TVQ_Thread();
        TVQ_Thread *job_thread3 = new TVQ_Thread();
        TVQ_Thread *job_thread4 = new TVQ_Thread();
        TVQ_Thread *job_thread5 = new TVQ_Thread();
        //-----------------------------------------------
        //TVQ_Thread *send_thread = new TVQ_Thread();                
// Create Thread        
        CreateListenThread(listen_thread,&thread_ctf);
        //-----------------------------------------------
        thread_ctf.us_ThreadID = 1;
        CreateJobThread(job_thread1,&thread_ctf);
        usleep(200);
        thread_ctf.us_ThreadID = 2;
        CreateJobThread(job_thread2,&thread_ctf);
        usleep(200);
        thread_ctf.us_ThreadID = 3;
        CreateJobThread(job_thread3,&thread_ctf);
        usleep(200);
        thread_ctf.us_ThreadID = 4;
        CreateJobThread(job_thread4,&thread_ctf);
        usleep(200);
        thread_ctf.us_ThreadID = 5;
        CreateJobThread(job_thread5,&thread_ctf);    //-----------------------------------------------------------------------------    bool CreateJobThread(TVQ_Thread *jb_thread,TVQ_THREAD_CONTROL *lock)
{
        TVQ_THREAD_CONTROL *ctf = static_cast(lock);
        cout << "Create Job Thread-" << ctf->us_ThreadID << endl;        
        jb_thread->Create(&Job_Thread,lock);
        return true;        
}    //-----------------------------------------------------------------------------
void *Job_Thread(void *param)
{        
        TVQ_THREAD_CONTROL *ctf = static_cast(param);
        TVQ_DOJOB *tjob = new TVQ_DOJOB(ctf->us_ThreadID);
        cout << "Run Job thread-" << ctf->us_ThreadID << endl;
        while(1)
        {
                usleep(100);
                tjob->Run(param);
        }
}
//-----------------------------------------------------------------------------

則會列出 Create Job Thread-1 Run Job thread-1 Create Job Thread-2 Run Job thread-2 Create Job Thread-3 Run Job thread-3 Create Job Thread-4 Run Job thread-4 Create Job Thread-5 Run Job thread-5 但是如果把usleep(200);拿掉

         thread_ctf.us_ThreadID = 1;
        CreateJobThread(job_thread1,&thread_ctf);
        thread_ctf.us_ThreadID = 2;
        CreateJobThread(job_thread2,&thread_ctf);
        thread_ctf.us_ThreadID = 3;
        CreateJobThread(job_thread3,&thread_ctf);
        thread_ctf.us_ThreadID = 4;
        CreateJobThread(job_thread4,&thread_ctf);
        thread_ctf.us_ThreadID = 5;
        CreateJobThread(job_thread5,&thread_ctf);

會變成 Create Job Thread-1 Create Job Thread-2 Create Job Thread-3 Create Job Thread-4 Create Job Thread-5 Run Job thread-5 Run Job thread-5 Run Job thread-5 Run Job thread-5 Run Job thread-5 似乎Thread一建立起來並不是馬上就執行的，這問題的癥結點在哪呢? 除了用usleep還有其他更好做法嗎? 因為用usleep程式啟動會慢一點點......
