deadline I need to run a bunch of threads, each with their own timer. Let's say I have a thread executing io_service::run, and is now invoking a completion handler of a deadline_timer. If it returns 1 then the wait handler was successfully cancelled. Nach dieser Antwort sollte dieser Code diese Arbeit erledigen: … Currently it's seems like deadline_timer available only in Boost.Asio because it use boost::posix_time::ptime. OPEN. The deadline associated with a timer may also be obtained as a relative time: boost::posix_time::time_duration time_until_expiry = t.expires_from_now (); or as an absolute time to allow composition of timers: deadline_timer t2 (i); t2.expires_at (t.expires_at () + boost::posix_time::seconds (30)); Boost If it returns 1 then the wait handler was successfully cancelled. deadline_timer - Asio C++ Library Cancels one asynchronous wait operation associated with the timer. 可以随时停止定时器。. You can find it here. 1 comment Comments . Dies führt dazu, dass der Timer sich selbst zerstört und abbricht, und ruft Ihre Funktion mit einem Fehlercode auf, den Sie ignorieren, wodurch die Endlosschleife verursacht wird. 写文章. c++ - io_service - Boost Asio Deadline_timer Copy link ghost commented Dec 30, 2020 @FerenczD commented on Sep 13, 2019, … Distinct … The boost:: asio:: basic_deadline_timer:: expires_from_now function cancels any pending asynchronous waits, and returns the number of asynchronous waits that were cancelled. boost asio deadline_timer数量多的时候有没有问题？ 我现在做一个服务器用boost asio做的。 现在我想每一个客户端连接之后创建一个deadline_timer，用来的主要目的就是让异步收包和发送在指… Selecting the maximum value from series of polygons that … boost::asio::deadline_timer (understand) - Programmer All Boost Apparently when the program runs to socket.receive_from(), it is blocked and the timer is never called because both … Boost.Asio定时器使用示例 - 简书 我正在使用 boost::asio::deadline_timer 添加套接字超时选项。我已经实现了异步 HTTP 读取，并且在我开始与服务器连接时启动了deadline_timer，并且在每次回调时，我都使用函数deadline_timer::expires_from_now 重置了deadline_timer。在deadline_timer 的错误处理程序中，我 … When calling this function, we pass in the print callback handle defined above. If it returns 0 then you were too late and the wait handler has already been executed, or will soon be executed. basic_deadline_timer::rebind_executor 타이머 유형을 다른 실행기(executor)로 다시 바인드한다. deadline_timer和socket一样，都用io_service作为构造函数的参数。也即，在其上进行异步操作，都将导致和io_service所包含的iocp相关联。这同样意味着在析构 io_service之前，必须析构关联在这个io_service上的deadline_timer。
