About This Guide
The System Architecture guide accompanies the QNX Neutrino realtime OS and is intended for both application developers and end-users.
The guide describes the philosophy of QNX Neutrino and the architecture used to robustly implement the OS. It covers message-passing services, followed by the details of the microkernel, the process manager, resource managers, the Photon microGUI, and other aspects of QNX Neutrino.
 |
Note that certain features of the OS as described in this
guide may still be under development for a given release.
For the latest news and information on any QNX product, visit our website (www.qnx.com). You'll find links to many useful areas -- software downloads, featured articles by developers, newsgroups, technical support options, and more. |
