Usage example of boost::condition::timed_wait
提问by Cookie
Does someone have an example of how to most easily use boost::condition::timed_wait? There are some threads on the topic here, hereand here, but none feature a working example. And boost doc is as usual quite sparse.
有人有一个如何最轻松地使用 boost::condition::timed_wait 的例子吗？此处、此处和此处有一些关于该主题的主题，但没有一个提供工作示例。boost doc 和往常一样非常稀疏。

Actually, I finally found a link with full example here. With a bit of adapting, this seems to be the call.
实际上，我终于在这里找到了完整示例的链接。稍加调整，这似乎就是决定性的。
boost::system_time const timeout=boost::get_system_time()+ boost::posix_time::milliseconds(35000);
boost::mutex::scoped_lock lock(the_mutex);
if(the_condition_variable.timed_wait(lock,timeout,&CondFulfilled))
{
<cond fulfilled code>
}
else
{
<timeout code>
}
bool CondFulfilled() { ... }
