C++ 中最好、最准确的计时器是什么?

What is the best, most accurate timer in C++?

推荐答案

这个问题的答案是特定于平台的.操作系统负责跟踪时间，因此，C++ 语言本身不提供用于执行此操作的语言结构或内置函数.

The answer to this is platform-specific. The operating system is responsible for keeping track of timing and consequently, the C++ language itself provides no language constructs or built-in functions for doing this.

但是，这里有一些平台相关计时器的资源:

However, here are some resources for platform-dependent timers:

• Windows API - SetTimer:http://msdn.microsoft.com/en-us/library/ms644906(v=vs.85).aspx
• Unix - setitimer: http://linux.die.net/man/2/setitimer

• Windows API - SetTimer: http://msdn.microsoft.com/en-us/library/ms644906(v=vs.85).aspx
• Unix - setitimer: http://linux.die.net/man/2/setitimer

跨平台解决方案可能是boost::asio::deadline_timer.

A cross-platform solution might be boost::asio::deadline_timer.
