关于 C++ 的问题定时器
我目前正在开发一个项目，该项目将像亚马逊或 Ebay 等规模非常小的在线销售网站一样。我想知道是否有人可以为我指明如何使用 C++ 定时器的正确方向。目前正在学习套接字编程，并试图在有人出售其产品时将计时器纳入拍卖时间。
谢谢
I am currently working on a project that will act like a Online selling website such as Amazon, or Ebay in a very small scale. I was wondering if anyone could point me in the right direction on how to use Timers for C++. Learning Socket Programming at the moment, and was trying to incorporate the timer for the auction time when someone is selling their product.
Thanks

你的意思是像timer_create？
你如何处理你的套接字？线程还是
选择？如果是后者（或类似 select 的东西），timer_create 将是一个自然的选择。You mean like timer_create?
How are you handling your sockets? Threads or
select? If the latter (or something like select), timer_create will be a natural fit.C++没有内置定时器。您愿意使用哪些库确实会影响您的答案。
操作系统将具有内置计时器，其他库（如 Boost）（在另一个答案中提到）或工具包（如 Qt）或运行时系统（如 .NET）也将具有可用的计时器。
我建议您在继续之前更详细地描述您的环境。
您使用什么套接字？如果它是一个相对知名的 API，它也可能有一个计时器实现。旁注：您还需要研究用于套接字的线程。
C++ does not have built-in timers. What libraries you are willing to use really makes the difference in your answer.
Operating systems will have built-in timers, other libraries like Boost (mentioned in another answer), or toolkits like Qt or runtime systems like .NET will also have timers available.
I recommend you describe your environment in more detail before moving on.
What are you using for the Sockets? If it's a relatively well-known API, it will likely have a timer implementation as well. side note: You'll also want to look into threads to use for your sockets.
boost::asio 计时器，或 boost 计时器库 (http: //www.boost.org/doc/libs/1_40_0/libs/timer/index.html）。或者只使用本机操作系统计时器功能，例如，在 Windows 中，它是 SetTimer 和 KillTime。
boost::asio timers, or the boost timer library (http://www.boost.org/doc/libs/1_40_0/libs/timer/index.html). Or just use the native OS timer functionalities, e.g., in Windows it'll be SetTimer and KillTime.
