Bestselling UNIX author W. Richard Stevens offers application developers and system programmers his professional, experience-based guidance on using the system call interface with C. In the first half of the book, Stevens describes more than 200 system calls and functions with a brief example program following each description. Having provided the basics, Stevens moves on to chapter-long examples. The book is applicable to all major UNIX releases, especially System V Release 4-including Solaris 2-and 4.4 BSD, including 386 BSD.
