Because a block device’s total size is fixed and easy to index, processes have random access to any block in the device with the help of the kernel. 程序以固定的块大小从块设备中访问数据。 上述示例中的sda1是一个磁盘设备,也是一种块设备。 磁盘可以被分割成数据块。 由于块设备的总大小是固定...

Implement a functionvoid reverse(char* str)in C or C++ which reverses a null-terminated string. This is (implicitly) asking for an in-place reversal of the string. We start by finding the end of the string (or equivalently, its length). Then we swap the last character and the first ch...
At some point, init starts a process allowing you to log in, usually at the end or near the end of the boot.This chapter covers the first four stages, focusing on the kernel and boot loaders. Chapter 6 continues with the user space start. ...
Program to swap numbers without using temporary variable in C#include <stdio.h> int main() { //variable declarations int a,b; //Input values printf("Enter the value of a: "); scanf("%d",&a); printf("Enter the value of b: "); scanf("%d",&b); //Numbers before swapping printf...
“ $ # include <string.h>” since we will be dealing with the strings and the string operation in this example. Now we will move forward to the next step, where we will declare the main function that will have a return type as an integer, and in this main function, we will write ...
You now know the physical and logical structure of a Linux system, what the kernel is, and how to work with processes. This chapter will teach you how the kernel starts— or boots. In other words, you’ll learn how the kernel moves into memory up to the point where the first user pr...
Swapis an area on a hard drive that has been designated as a place where the operating system can temporarily store data that it can no longer hold in RAM. Basically, this gives you the ability to increase the amount of information that your server can keep in its working "memory", with...
