7.5 Conclusions

7.5  Conclusions

This chapter has discussed inter-process communication using pipes and sockets. Sockets are explained in great detail although we do not discuss Perl’s built-in sockets. We discuss Perl modules that make socket programming a lot easier. In this chapter, we also discuss how processes can be created on a Unix system using fork and how forking can help us write more powerful and more useful socket programs. Sockets work on Windows
and pre-OS X Macintosh systems as well although the details may vary from what is discussed in this book.
