http://support.qnx.com/developers/docs/6.5.0/topic/com.qnx.doc.neutrino_utilities/p/pidin.html As a microkernel-based OS, QNX is based on the idea of running most of the operating system kernel in the form of a number of small tasks, named Resource Managers. This differs from the more traditional monolithic kernel, in which the operating system kernel is one very large program composed of a huge number of parts, with special abilities. In the case of QNX, the use of a microkernel allows users (developers) to turn off any functions they do not need without having t… duotone slick 6.0 https://mlok-host.com
