How to use this guide

This User's Guide describes the Integrated Development Environment (IDE), which is part of the QNX Momentics development suite. The guide introduces you to the IDE and shows you how to use it effectively to build your QNX Neutrino-based systems.

The workflow diagram above shows how the guide is structured and suggests how you might use the IDE. Once you understand the basic concepts, you're ready to begin the typical cycle of setting up your projects, writing code, debugging, testing, and finally fine-tuning your target system.

Each chapter begins with the workflow diagram, but with the chapter's bubble highlighted to show where you are in the book. Note that in the online version each bubble is a link.

Note: This release of the IDE is based on Eclipse 3.2. If you have an older version of the IDE, see the Migrating from Earlier Releases appendix in this guide.

This guide assumes the following:

Copyright © 2002-2007, QNX Software Systems GmbH & Co. KG. All rights reserved.

Throughout this manual, we use certain typographical conventions to distinguish technical terms. In general, the conventions we use conform to those found in IEEE POSIX publications. The following table summarizes our conventions:

Reference Example
Code examples if( stream == NULL )
Command options -lR
Commands make
Environment variables PATH
File and pathnames /dev/null
Function names exit()
Keyboard chords Ctrl-Alt-Delete
Keyboard input something you type
Keyboard keys Enter
Program output login:
Programming constants NULL
Programming data types unsigned short
Programming literals 0xFF, "message string"
Variable names stdin
User-interface components Cancel

We use an arrow (-->) in directions for accessing menu items, like this:

You'll find the Other... menu item under Perspective-->Show View.

We use notes, cautions, and warnings to highlight important messages:

Note: Notes point out something important or useful.

Caution: Cautions tell you about commands or procedures that may have unwanted or undesirable side effects.

WARNING: Warnings tell you about commands or procedures that could be dangerous to your files, your hardware, or even yourself.

Note to Windows users

In our documentation, we use a forward slash (/) as a delimiter in all pathnames, including those pointing to Windows files.

We also generally follow POSIX/UNIX filesystem conventions.

Navigation buttons
