What you'll find in this guide

The Neutrino Programmer's Guide is intended for developers who are building applications that will run under the QNX Neutrino Realtime Operating System.

Depending on the nature of your application and target platform, you may also need to refer to Building Embedded Systems. If you're using the Integrated Development Environment, see the IDE User's Guide. For a different perspective on programming in Neutrino, see Getting Started with QNX Neutrino: A Guide for Realtime Programmers.

This table may help you find what you need in the Programmer's Guide:

When you want to:	Go to:
Get started with a “Hello, world!” program	Compiling and Debugging
Get an overview of the Neutrino process model and scheduling methods	Programming Overview
Create and terminate processes	Processes
Understand the inaccuracies in times	Tick, Tock: Understanding the Neutrino Microkernel's Concept of Time
Use native networking	Transparent Distributed Processing Using Qnet
Learn about ISRs in Neutrino	Writing an Interrupt Handler
Analyze and detect problems related to dynamic memory management	Heap Analysis: Making Memory Errors a Thing of the Past
Deal with non-x86 issues (e.g. big-endian vs little-endian)	Freedom from Hardware and Platform Dependencies
Understand our `Makefile` methodology	Conventions for Recursive Makefiles and Directories
Learn how to use the GDB debugger	Using GDB
Find out about using memory on ARM targets	ARM Memory Management
Find out about advanced Qnet topics	Advanced Qnet Topics
Look up terms used in the Neutrino documentation	Glossary

We assume that you've already installed Neutrino and that you're familiar with its architecture. For a detailed overview, see the System Architecture manual.

Typographical conventions

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:

Notes point out something important or useful.

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

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

At the top and bottom of our HTML docs, you'll see some or all of these buttons:

Use this button:	To move:
	To the previous part of the document.
	“Up” in the document: In a prose book, this typically takes you to About This Guide. In a reference book, it takes you to the listing of items that start with a given letter. For example, if you're looking at the docs for abs(), this button takes you to the listing of the functions that start with `A`.
	To the keyword index.
	To the next part of the document.
