It’s been almost eight years since I first updated Advanced Programming in the UNIX Environment, and already so much has changed.
- Before the second edition was published, The Open Group created a 2004 edition of the Single UNIX Specification, folding in the changes from two sets of corrigenda. In 2008, The Open Group created a new version of the Single UNIX Specification, updating the base definitions, adding new interfaces, and removing obsolete ones. This was called the 2008 version of POSIX.1, which included version 7 of the Base Specification and was published in 2009. In 2010, this was bundled with an updated curses interface and reissued as version 4 of the Single UNIX Specification.
- Versions 10.5, 10.6, and 10.8 of the Mac OS X operating system, running on Intel processors, have been certified to be UNIX® systems by The Open Group.
- Apple Computer discontinued development of Mac OS X for the PowerPC platform. From Release 10.6 (Snow Leopard) onward, new operating system versions are released for the x86 platform only.
- The Solaris operating system was released in open source form to try to compete with the popularity of the open source model followed by FreeBSD, Linux, and Mac OS X. After Oracle Corporation bought Sun Microsystems in 2010, it discontinued the development of OpenSolaris. Instead, the Solaris community formed the Illumos project to continue open source development based on OpenSolaris. For more information, see http://www.illumos (dot) org.
- In 2011, the C standard was updated, but because systems haven’t caught up yet with the changes, we still refer to the 1999 version in this text.
Most notably, the platforms used in the second edition have become out-of-date. In this book, the third edition, I cover the following platforms:
1. FreeBSD 8.0, a descendant of the 4.4BSD release from the Computer Systems Research Group at the University of California at Berkeley, running on a 32-bit Intel Pentium processor.
2. Linux 3.2.0 (the Ubuntu 12.04 distribution), a free UNIX-like operating system, running on a 64-bit Intel Core i5 processor.
3. Apple Mac OS X, version 10.6.8 (Darwin 10.8.0) on a 64-bit Intel Core 2 Duo processor. (Darwin is based on FreeBSD and Mach.) I chose to switch to an Intel platform instead of continuing with one based on the PowerPC, because the latest versions of Mac OS X are no longer being ported to the PowerPC platform. The drawback to this choice is that the processors covered are now slanted in favor of Intel. When discussing issues of heterogeneity, it is helpful to have processors with different characteristics, such as byte ordering and integer size.
4. Solaris 10, a derivative of System V Release 4 from Sun Microsystems (now Oracle), running on a 64-bit UltraSPARC IIi processor.
