Working with Events (Embedded SQL Guide)

Go Up to Embedded SQL Guide

This chapter describes the InterBase event mechanism and how to write applications that register interest in and respond to events. The event mechanism enables applications to respond to actions and database changes made by other, concurrently running applications without the need for those applications to communicate directly with one another, and without incurring the expense of CPU time required for periodic polling to determine if an event has occurred.
