# 11 Programming Tips & Examples

This chapter provides information on parsing address information blocks and advanced programming technique in UNIX.This chapter also explains calls into the SwitchKit API which are necessary for a call processing application. The examples provide a template for building your own call processing application.

Important! The object of the section showing examples is not to provide a complete call processing solution.

The actual code for the sample applications can be found in the installation directory in samples and the configuration file can be found in samples/cfg. The demonstration contains two processes, SimpleTandem and CallSim that run in conjunction with each other, whereby SimpleTandem answers calls that have been initiated by CallSim.
