Os X And Ios Kernel Programming

OS X and iOS Kernel Programming combines essential operating system and kernel architecture knowledge with a highly practical approach that will help you write effective kernel-level code. You’ll learn fundamental concepts such as memory management and thread synchronization, as well as the I/O Kit framework. You’ll also learn how to write your own kernel-level extensions, such as device drivers for USB and Thunderbolt devices, including networking, storage and audio drivers. OS X and iOS Kernel Programming provides an incisive and complete introduction to the XNU kernel, which runs iPhones, iPads, iPods, and Mac OS X servers and clients. Then, you’ll expand your horizons to examine Mac OS X and iOS system architecture. Understanding Apple’s operating systems will allow you to write efficient device drivers, such as those covered in the book, using I/O Kit. With OS X and iOS Kernel Programming, you’ll: Discover classical kernel architecture topics such as memory management and thread synchronization Become well-versed in the intricacies of the kernel development process by applying kernel debugging and profiling tools Learn how to deploy your kernel-level projects and how to successfully package them Write code that interacts with hardware devices Examine easy to understand example code that can also be used in your own projects Create network filters Whether you’re a hobbyist, student, or professional engineer, turn to OS X andiOS Kernel Programming and find the knowledge you need to start developing

An in-depth look into Mac OS X and iOS kernels Powering Macs, iPhones, iPads and more, OS X and iOS are becoming ubiquitous. When it comes to documentation, however, much of them are shrouded in mystery. Cocoa and Carbon, the application frameworks, are neatly described, but system programmers find the rest lacking. This indispensable guide illuminates the darkest corners of those systems, starting with an architectural overview, then drilling all the way to the core. Provides you with a top down view of OS X and iOS Walks you through the phases of system startup—both Mac (EFi) and mobile (iBoot) Explains how processes, threads, virtual memory, and filesystems are maintained Covers the security architecture Reviews the internal Apis used by the system—BSD and Mach Dissects the kernel, XNU, into its sub components: Mach, the BSD Layer, and I/o kit, and explains each in detail Explains the inner workings of device drivers From architecture to implementation, this book is essential reading if you want to get serious about the internal workings of Mac OS X and iOS.

Now that multicore processors are coming to mobile devices, wouldn't it be great to take advantage of all those cores without having to manage threads? This concise book shows you how to use Apple's Grand Central Dispatch (GCD) to simplify programming on multicore iOS devices and Mac OS X. Managing your application’s resources on more than one core isn't easy, but it's vital. Apps that use only one core in a multicore environment will slow to a crawl. If you know how to program with Cocoa or Cocoa Touch, this guide will get you started with GCD right away, with many examples to help you write high-performing multithreaded apps. Package your code as block objects and invoke them with GCD Understand dispatch queues—the pools of threads managed by GCD Use different methods for executing UI and non-UI tasks Create a group of tasks that GCD can run all at once Instruct GCD to execute tasks only once or after a delay Discover how to construct your own dispatch queues

Considered a classic by an entire generation of Mac programmers, Dave Mark's Learn C on the Mac has been updated for you to include Mac OS X Mountain Lion and the latest iOS considerations. Learn C on the Mac: For OS X and iOS, Second Edition is perfect for beginners learning to program. It includes contemporary OS X and iOS examples! This book also does the following: Provides best practices for programming newbies Presents all the basics with a pragmatic, Mac OS X and iOS -flavored approach Includes updated source code which is fully compatible with latest Xcode After reading this book, you'll be ready to program and build apps using the C language and Objective-C will become much easier for you to learn when you're ready to pick that up. What you'll learn Master C programming, the gateway to programming your Mac, iPhone or iPad Write apps for the contemporary Mac OS X interface, the cleanest user interface around Write apps for the modern iOS interface, one of the two most popular mobile platforms in the world Understand variables and how to design your own data structures Work with the file system Connect to data sources and the Internet How to handle error handling and much more Who this book is for For anyone wanting to learn to program in Mac OS X and iOS, including developers new to the Mac and iPhone/iPad, developers new to C, or students entirely new to programming.

This book follows a recipe-based approach that will heavily focus on the code and how to integrate the samples with the reader’s projects.Each recipe consists of one or more methods that you can put directly into your app and use. This book is ideal for developers that want to create network applications for the Apple OS X or iOS platforms. All examples are written in Objective-C using XCode as the IDE. Knowledge of Objective-C and X-Code is essential.

Provides a strong foundation of cybercrime knowledge along with the core concepts of networking, computer security, Internet of Things (IoTs), and mobile devices. Addresses legal statutes and precedents fundamental to understanding investigative and forensic issues relative to evidence collection and preservation. Identifies the new security challenges of emerging technologies including mobile devices, cloud computing, Software-as-a-Service (SaaS), VMware, and the Internet of Things. Strengthens student understanding of the fundamentals of computer and network security, concepts that are often glossed over in many textbooks, and includes the study of cybercrime as critical forward-looking cybersecurity challenges.

What does it take to build an iPhone app with stunning 3D graphics? This book will show you how to apply OpenGL graphics programming techniques to any device running the iPhone OS -- including the iPad and iPod Touch -- with no iPhone development or 3D graphics experience required. iPhone 3D Programming provides clear step-by-step instructions, as well as lots of practical advice, for using the iPhone SDK and OpenGL. You'll build several graphics programs -- progressing from simple to more complex examples -- that focus on lighting, textures, blending, augmented reality, optimization for performance and speed, and much more. All you need to get started is a solid understanding of C++ and a great idea for an app. Learn fundamental graphics concepts, including transformation matrices, quaternions, and more Get set up for iPhone development with the Xcode environment Become familiar with versions 1.1 and 2.0 of the OpenGL ES API, and learn to use vertex buffer objects, lighting, texturing, and shaders Use the iPhone's touch screen, compass, and accelerometer to build interactivity into graphics applications Build iPhone graphics applications such as a 3D wireframe viewer, a simple augmented reality application, a spring system simulation, and more

So, you're one of the many, the proud... the Unix geeks who've "switched" to Mac OS X. Although hacking code on the Mac is the same as hacking code on other Unix systems, you're bound to run into some problems because of the subtle differences between the Unix you're accustomed to and how things are done in Mac OS X 10.2 (Jaguar). Mac OS X for Unix Geeks was written by two long-time Unix users who've found themselves exactly where you are. It cuts through the chaff and gets right to the point on such topics as : • Using the Terminal and understanding how it differs from an xterm • Using Directory Services, Open Directory (LDAP), and NetInfo • Compiling code with GCC 3 • Library linking and porting Unix software • Creating and installing packages with Fink • Building the Darwin kernel • Running X Windows on top of Mac OS X This quick and dirty guide continues with an overview of Mac OS X's filesystem and startup processes, wrapping up with a handy reference section called the "Missing Manpages", covering Mac OS X commandline utilities not in the official documentation. Mac OS X is quickly becoming the platform of choice for Unix hackers and geeks, because it gives you what Tim O'Reilly refers to as "guilt-free computing"- a Unix system that you don't have to share with Windows. If you proudly wear the badge "Unix Geek", this book is your guide to demystifying the geekier side of Mac OS X.
