Summary

In this chapter, you learned about the ndbm(3) set of routines. With the working SnapShot program and the Dbm and InoDb classes, you saw how the NDBM database routines were applied to a real-world application. The NDBM routines are ideal for small applications where multiuser contention is not an issue.

The next chapter covers the topic of UNIX signals. Signals permit you to process asynchronous events in your program.
