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 Toolkit for Visual Studio Code
This User's Guide describes the QNX^® Toolkit for Visual Studio Code. The guide introduces you to the QNX Toolkit by explaining the QNX development environment and how to build, run, and debug your QNX^® Operating System (OS) applications and systems.
QNX Hypervisor and QNX Hypervisor for Safety
The QNX Hypervisor and QNX Hypervisor for Safety products allow 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.
Typographical Conventions, Support, and Licensing
This section describes the typographical conventions used throughout the documentation, explains how to obtain technical support, and provides some information about licensing.

Introspection API

Note:

All functions that take a pid64_t (64-bit) parameter also accept a pid_t (32-bit) value, where:

pid = (pid_t)pid64;
pid64 = getpid64(pid);

Refer to getpid64() for more information.

This chapter describes the introspection APIs defined in the introspection.h header file. Its corresponding static library, libintrospection, wraps the following kernel messages:
