Book description
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.
