About This Guide


A real-time program is one that must maintain a fixed timing relationship to external hardware. In order to respond to the hardware quickly and reliably, a real-time program must have special support from the system software and hardware.

This guide describes the support that IRIX(TM) and the Silicon Graphics CHALLENGE(TM), Onyx(TM), and POWERCHALLENGE computers provide to real-time programs. The support bundled with all versions of IRIX is called REACT(TM). A set of extra-cost features is called REACT/Pro(TM). This guide covers REACT for IRIX 6.2, and REACT/Pro 3.0.

This guide is designed to be read online, using IRIS InSight(TM). You are encouraged to read it in non-linear order using all the navigation tools that Insight provides. In the online book, the name of a reference page ("man page") is red in color (for example: mpin(2), sproc(2)). You can click on these names to cause the reference page to open automatically in a separate terminal window.
