# amshello(1)

Asynchronous Message Service (AMS) demo program for UNIX

## NAME

amshello - Asynchronous Message Service (AMS) demo program for UNIX

## SYNOPSIS

**amshello**

## DESCRIPTION

**amshello** is a sample program designed to demonstrate that an entire (very simple) distributed AMS application can be written in just a few lines of C code.  When started, **amshello** forks a second process and initiates transmission of a "Hello" text message from one process to the other, after which both processes unregister and terminate.

The **amshello** processes will register as application modules in the root unit of the venture identified by application name "amsdemo" and authority name "test".  A configuration server for the local continuum and a registrar for the root unit of that venture (which may both be instantiated in a single **amsd** daemon task) must be running in order for the **amshello** processes to run.

## EXIT STATUS

- "0"

  **amshello** terminated normally.

## FILES

A MIB initialization file with the applicable default name (see [*amsrc*(5)](/amsrc/5.md)) must be present.

## ENVIRONMENT

No environment variables apply.

## DIAGNOSTICS

No diagnostics apply.

## BUGS

Report bugs to \<ion-bugs@korgano.eecs.ohiou.edu\>
