前些日子小绿做了一些高翔slam前端部分的代码解读，其中遇到g2o的部分基本上就黑箱化略过了。然而g2o是...
structsteady_clock; Remarks Asteady_clockis a monotonic clock, which means that the time it reports only moves forward. The value returned by a call tonowis always less than or equal to the value that is returned by the next call tonow. ...
今天无意中发现调整系统时间时导致服务器的注册机制失效了,一查发现原来是使用的std::steady_clock并非真正的steady,它在头文件声明如下: classsteady_clock :publicsystem_clock {//wraps monotonic clockpublic:staticconstboolis_monotonic =true;//retainedstaticconstboolis_steady =true; }; typedef steady_clock ...
class steady_clock : public system_clock; RemarksA clock is monotonic if the value that is returned by a first call to now() is always less than or equal to the value that is returned by a subsequent call to now().A clock is steady if it is monotonic and if the time between clock...
std::chrono::steady_clock Defined in header<chrono> classsteady_clock; (since C++11) Classstd::chrono::steady_clockrepresents a monotonic clock. The time points of this clock cannot decrease as physical time moves forward and the time between ticks of this clock is constant. This clock is ...
system_clock::is_monotonic 保存true。steady_clock是“单调的” 。 system_clock::is_steady 保存true。steady_clock是“稳定的” 。 要求 Header:chrono Namespace:std::chrono 请参见 参考 <chrono> system_clock 结构 其他资源 C++ 标准库头文件
是Boost.Asio 库中提供的一个定时器类,它使用单调时钟(monotonic clock)来确保即使在系统时间被修改的情况下,定时器的行为也是稳定和可靠的。这个定时器通常用于需要精确时间间隔的场景,比如心跳检测、超时处理等。 2. async_wait成员函数的作用 async_wait 是boost::asio::steady_timer 类的一个成员函数,它用于异...
In the STL (version 14.27.29009) included with VS Version 16.7.0 Preview 3.1, the steady_clock is not monotonic (the clock goes backwards after ~15 minutes). This is a critical bug which breaks every application using steady_clock. Windows 10.0.19042.330 on bare metal I can confirm that...
