The System Architecture guide accompanies the QNX Neutrino RTOS and is intended for both application developers and end-users.
This 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, and other aspects of the OS.
