About the QNX OS Programmer's Guide

QNX SDP8.0Programmer's GuideDeveloper

The QNX OS Programmer's Guide covers a variety of topics that might interest developers who are building applications that will run under the QNX OS.

Note: For an introduction to programming in QNX OS, see Getting Started with the QNX OS. 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.
