Chapter 7. Handling Events and Multiple I/O Streams

Many applications, such as the server example in Chapter 6, can benefit greatly from a simple way to handle multiple events easily and efficiently. Event handling often takes the form of an event loop that continually waits for events to occur, decides what actions need to be taken, and dispatches control to other functions or methods appropriate to handle the event(s). In many networked application projects, the event-handling code is often the first piece of the system to be developed, and it's often developed over and over for each new project, greatly adding to the time and cost for many projects.

The ACE Reactor framework was designed to implement a flexible event-handling mechanism in ...
