我觉得好，跨平台相当于win32的事件是的的boost ::条件的，所以你的code可能是这个样子：

I think a good, cross-platform equivalent to win32 events is boost::condition, so your code could look something like this:

void foo()
{
    boost::mutex mtxWait; 
    boost::condition cndSignal;

    bCall(boost::bind(&bar, mtxWait, cndSignal));

    boost::mutex::scoped_lock mtxWaitLock(mtxWait);
    cndSignal.wait(mtxWait); // you could also use cndSignal.timed_wait() here
}

void bar(boost::mutex& mtxWait, boost::condition& cndSignal)
{
    doSomething();
    cndSignal.notify_one();
}
