 | | Just as we began this book with a discussion of the numerous little functions that you've probably used every day, we finish the book with a discussion of a number of functions that you may not use every day, but that are just as useful. The number of functions available to the systems programmer grows with every release of UNIX. Some of the new functions are useful, and others are less so. As new functions are added, some of them catch on and start to show up in lots of programs. These functions tend to start propagating to other versions of UNIX, as programmers demand them. Other functions are added and then later removed, as their use never catches on or as better replacements are developed. | |
