When we only fork () once, there are parent processes and child processes. There are two ways to avoid creating a zombie process: The parent process invokes functions such as Waitpid () to receive the child process exit status. The parent process ends first, and the child process is automatically hosted to the init process (PID = 1). Currently, consider the case where the child process ended before the parent process: If the parent process does no

To exit the U disk, click the "Safely Remove Hardware" icon at the bottom right, a dialog box will pop up, "Now cannot stop the ' universal volume" device, please stop the device later. Some friends are afraid of pulling the U disk directly after the U disk in the data will be lost. In fact, this time did not open U disk files, u disk is normal, but why this problem, the direct pull out of the data will not be lost, the following to explain how to solve this situation and to

When users use laptops and DVD drives to see the CD, the power consumption of the battery is relatively large. Users want to see DVDs, you can copy the data to the hard disk, so that not only can improve reading speed, but also can improve the computer's standby time. When a laptop uses a battery, if a lot of USB devices are used, such as a removable hard disk, a camera, etc., these devices can also reduce the battery's use time because they are mostly powered by the notebook computer it

In the game we use collision detection, when two objects collide to produce sound sound effects, the code is as follows:If you use the above code, we will find that the sound is declared in the script using Audiosource, and the sound stops immediately when the object is destroyed.But we want the sound to continue to play, so at this point we should use the AudioClip declaration with the following code:Public Audiosource Music_pickup;void Ontriggleenter (Collider other){Player player = other.

The double type and float type are primarily designed for use in scientific and engineering calculations and are used for binary floating-point calculations. For the general calculation is usually inaccurate results, so for the ordinary floating-point addition and subtraction, the solution needs to use Int,long,bigdecimal to calculate. 1. Calculate the problem?The calculation results are as follows:Obviously the result is not what we need. The result we need is: 0.88So, our program should write

If you find that an interface is used with the following definition method: Public string[] GetParameters (); Then you should seriously reflect. Arrays are not just old-fashioned, and we have reasonable grounds to avoid exposing them. In this article, I will try to summarize the pitfalls of using arrays in the Java API. Let's start with one of the most surprising examples.array causes poor performance You might think that using arrays i
