set timer for 1 minute

Today, I sent a question to my microblog: In my interview, I often ask a question: "How to set a 30-minute session expired?", we do not think that seemingly simple, here bread contains a lot of knowledge, especially suitable for the examination of the basic skills is solid, who will answer to try? Oh Why do you ask this question? 1. I saw someone discuss the i

Yesterday morning when viewing the Zabbix monitoring interface, the number of processes found on one of the servers and the 1-minute load had reached a very alarming number, the Zabbix default alarm value was the number of processes in the 5-minute average of more than 1000, and the 1-

task that needs to be executed repeatedly at the same time every day cannot be planned directly using timer, because a time jump occurs at the start and end of the Failover. This article demonstrates a general timer and timertask planning framework that allows more flexible task scheduling. This framework is very simple-it includes two classes and one interface-and is easy to grasp. If you are used to usin

multiple channels can be accurately synchronized. If there is no shadow register, or preload Register and shadow register are passed through, that is, when the software updates the preload register, the shadow register is also updated, because the software cannot update multiple registers at the same time, as a result, the time sequence of multiple channels cannot be synchronized. If other factors (such as interruptions) are added, the time sequence relationship of multiple channels may be unpr

Introduction to timer subsystem in linux subsystem set (2) I have not translated an article in my blog. Although the English level is limited, it is also a good choice to translate an article slowly using google translation. Let's take a look at the hrtimer documentation.

You can use the settimer function to assign a timer to your windows program. settimer contains an unsigned integer parameter, which specifies the duration of the interval, in milliseconds. This function sends a wm_timer message to your program at a specified interval; The timer message is not asynchronous. Because timers are interrupted Based on hardware timers, programmers are sometimes misled to think tha

For example: if ("mid" = document.activeElement.id) {alert ();}, "Mi

Set up timed tasks (Introduction to the Timer Class)In many of our projects, we need to use timed tasks, so we would like to take this blog to introduce a timed task.To set a scheduled task, proceed as follows: First new Timer object Timer

is, Hz. The hardware is set according to the Hz value when the system starts. The system structure is different, and the Hz value is also different. The arm is 100Hz, and the i386 is 1000Hz. Increasing the beat rate means that the clock interruption is generated more frequently, so the interrupt processing program will be executed more frequently, which will bring the following benefits to the entire system:
