Getting started with the documentation

After you've installed QNX SDP 6.4.1, you'll find an extensive set of online documentation in HTML format. You can read it in the Integrated Development Environment's help system on Linux and Windows development hosts; on self-hosted QNX Neutrino systems, you can read it in the Photon helpviewer, or you can use a web browser to display:


This “roadmap” page contains links to the various HTML booksets that accompany the OS (e.g. System Architecture, QNX Neutrino Programmer's Guide, Library Reference, Utilities Reference, etc.), as well as 10 Steps to Developing a QNX Program: Quickstart Guide, a short tutorial that will help you get started.

For information about QNX SDP, including any host-specific issues, see the release notes. The online documentation includes a copy, but for for the most up-to-date version, go to our website,, log into your myQNX account, and then go to the Download area.
