Chapter 2: Utility Routines
Overview
This chapter examines most of the commonly used utility routines offered by the SVR4 C library, and gives brief examples of their use. The UNIX C library provides a large number of routines for performing common programming tasks such as comparing and copying strings, allocating memory, manipulating temporary files, and so forth. You are probably already familiar with many of these routines, but if you've been doing most of your programming in a BSD environment, several of them may be new to you. Many of these routines were first added to the C library in early versions of System V, and were later mandated by the ANSI C and POSIX standards. Since most commonly used versions of BSD UNIX predate these standards, these routines are often missing from those versions' C libraries.
