.SH "NAME"
ivy\-c \- a software bus library
.SH "SYNOPSIS"
Ivy\-c provides a useful set of C library functions for communicating between different
processes through a software bus
.SH "DESCRIPTION"
Ivy is a software bus, ie a system that allows any software component to freely exchange data.
The basic principle of a software bus is to ease the rapid implementation of new agents, and to manage a dynamic collection of agents on the bus: agents connect, send and receive messages, and disconnect without perturbing the overall functionment of the bus.
Each time an application initializes a connection on the bus, a
"ready" message is sent to all other applications already connected, and the
list of the messages subscribed by this application is dispatched.
The format for the messages is free.
