This book is one that any Solaris systems programmer will want on their shelf.

Sun Microsystems' Solaris Operating Environment boasts a significant installed

base, but the intricacies of programming in this UNIX environment have been

previously unaddressed in book format. In this thorough new book, the author

provides context that allows the reader to better understand the subtleties of

the Solaris Operating Environment. He explains not only the "how's" but also

the "why's" of Solaris programming, complete with a brief history of the

operating system. The result is a comprehensive text that Solaris practitioners

will refer to time and again as they face and overcome the significant challenges

of their everyday work.

Solaris Systems Programming

Rich Teer

The first definitive guide to programming in the Solaris Operating Environment

In the tradition of W. Richard Stevens' Advanced Programming in the UNIX Environment, this book offers comprehensive, practical guidance for systems programmers. It covers all versions of the Solaris OS, from 2.5 through 9 and is relevant to both SPARC™ and x86 platforms. From I/O to IPC, pseudo terminals to localization, and processes to doors, Rich Teer illuminates the unique features and subtleties of this environment as never before.

As a former Sun Microsystems, Inc. consultant, long-time C programmer, and tech reviewer for Stevens' UNIX Network Programming, Teer is singularly well qualified to write this book. Using real-world case studies, code examples, and diagrams, he explains both the "how" and "why" of Solaris systems programming—helping any C programmer write efficient, reliable code. Coverage includes:

  • Terminology and features used in Solaris systems programming
  • Fundamentals: utility functions, file I/O, standard I/O library, date/time operations, users/groups, system information, resource limits, and secure C programming
  • I/O in depth: files, directories, file systems, terminal I/O, and advanced I/O
  • Processes and process control: UNIX process environments, relationships, signals, and daemon processes
  • Interprocess communications: Pipes, FIFOs, System V IPC facilities, doors, and more
  • Appendices on internationalization, localization, and BSD source compatibility
  • Portability guidance: flags all features that are specific to Solaris®
