QNX Neutrino RTOS User's Guide
The QNX Neutrino User's Guide is intended for all users of a QNX Neutrino system, from system administrators to end users.
This guide tells you how to:
- Use the QNX Neutrino runtime environment, regardless of the kind of computer it's running on (embedded system or desktop). Think of this guide as the companion how-to doc for the Utilities Reference . Assuming there's a Neutrino system prompt waiting for input, this guide is intended to help you learn how to interact with that prompt.
- Perform such traditional system administration topics as setting up user accounts, security, starting up a Neutrino machine, etc.
The Neutrino User's Guide is intended for programmers who develop Neutrino-based applications, as well as OEMs and other resellers of the OS, who may want to pass this guide on to their end users as a way to provide documentation for the OS component of their product.
