- System Security Guide
  The QNX System Security Guide is intended for both system integrators who are responsible for the security of a QNX Neutrino RTOS system and developers who want to create a QNX Neutrino resource manager free from vulnerabilities.
- Utilities & Libraries
QNX Hypervisor
The QNX Hypervisor allows you to run multiple OSs on a target system so you can separate critical and non-critical functions, support a wide variety of applications, and reduce hardware costs.
QNX Software in the Cloud
QNX Software in the Cloud enables developers to use the QNX software in Amazon Web Services (AWS) and Microsoft Azure (Azure).
QNX Advanced Virtualization Frameworks User's Guide
This User's Guide is aimed at all systems integrators and developers who want to design and build embedded systems using the QNX Advanced Virtualization Frameworks.
Typographical Conventions, Support, and Licensing

Code Examples

To use a particular Networking Middleware service interface, your source files must include the service's header file (for compiling), and your makefile must provide the -l qwf_interface option to qcc (for linking against libqwf_interface).

Note:

Before you can use any function in a particular interface, you must initialize the service by calling qwf_Init() or the combination of qwf_InitializeCore() and qwf_InitializeServices().

The remaining sections in this chapter provide code examples for using specific services.
