Re: Thread and join

[Marcelo Dalmas]

So, how to suspend the execution of main thread to wait a thread?

With pthread i do:
main ()
{
        pthread_t *thread;

        pthread_create(thread);
        do something;
        pthread_join(thread);

        return 0;
}

Now, with CommonC++ I do:

main()
{
        MyThread *thread = new MyThread();

        thread->Start();
        do something;

        while ( thread->isRunning() )  // why not thread->Join() ?
                sleep(1);

        delete thread;
        return 0;
}

I don't think so. If there are two indepents things to do, like add
number, i could do :

                |
                ^
              /   \
        1+2+...   1+2+..
             \    /
               a+b
