Sleep ()Causes the current thread (that is, the thread that called the method) to suspend execution for a period of time, allowing other threads to continue executing, but it does not release the object lock.This means that if there is synchronized synchronization fast, other threads still cannot access the shared data.

task_uninterruptible ignores the signal, while a process in the task_interruptible state receives a signal that wakes up early and signals the signal. Processes in both states are on the same waiting queue, waiting for certain events to run.1. Waiting QueueHibernation is processed by waiting for a queue. The wait queue is a simple list of processes that wait for certain events to occur. The kernel uses wake_queue_head_t to represent the waiting queue. The wait queue can be created statically by

Now many people are starting to use the Win7 system, if you leave the computer for a period of time, do not want to shut down but also want to save electricity how to do, this tutorial for you to introduce the Win7 sleep settings skills. One, Windows7 fast sleep has a trick Click the Start menu, turn on the control Panel → hardware and sound → Power options. Click the Change schedule settings link next to

The meaning of Sleep (0) is to discard the current thread execution time slices and put itself in the waiting queue. At this point the other threads will get the time slice to program the program. Sleep (0) can reduce the execution speed of the current thread, such as: Now there are 100 threads in the system (assuming a thread bar) to perform different tasks, and they perform the same priority, and each tim

C language Pause () function: Let the process pause until the signal appearsheader file: #include To define a function: int pause (void); Function Description: Pause () will suspend the current process (go to sleep state) until it is interrupted by a signal (signal). Return value: Returns only-1. Error code: EINTR has a signal arrival interrupt this function. C language Alarm () function: Set signal transmission alarm Cl

　　Leave the computer for a while When using a computer at ordinary times, it is often the case that you may leave for a period of time, which may be long or short. It is not fixed, such as when you eat at noon or evening. At this time, if the computer is shut down, it seems a little difficult, because when it comes back, many programs, web pages have to be re-opened, but if it is not shut down, the computer is a waste of electricity, if there is another delay, it may not be necessary to change t

The recent poor quality of sleep, now analyzed the following reasons:Since the beginning of the senior high, feel sleep when there is a sound sleep, outside the rental, and then began to develop habits, have their own dislike of noise, will fall asleep difficult.But actually hears the sound to be able to sleep, for exa

Most people need to ensure 7 to 10 hours of sleep. The Stanford University Human Sleep Research Center recommends two methods to help you calculate how long you need to

When a process communicates in a blocking manner, the process suspends sleep before the result is obtained. In order to ensure that the process enters sleep in a safe way, we need to keep in mind two rules: 1. never enter sleep in the atomic context. 2. do not know the environment after the process is sleep. After waki

The URL is as follows: http://dis.4chan.org/read/prog/1295544264. Although the use value is not very high, it is impossible to find such a method to become a genius. Its basic idea is to sort a group of data based on the CPU scheduling algorithm. There cannot be negative values, in the thread, sleep
