This final part of the series will step outside the domain of standard C and investigate a pattern for event-driven applications. The REACTOR pattern decouples different responsibilities and allows applications to demultiplex and dispatch events from potentially many clients.

This part of the series will highlight another principle for dependency management and illustrate how both of these principles may be realized in C using the OBSERVER pattern.

This part of the series will investigate a design pattern that adds flexibility to common software entities by letting clients customize and extend them without modifying existing code.
