Chapter 1 Introduction

Many programs use procedures or subroutines to handle recurring tasks. In the MPE/iX operating system many of these tasks are performed by a set of system procedures called intrinsics. Intrinsics are available to any process which has the capabilities required to call the intrinsic.

The tasks that intrinsics handle include:

Intrinsics are no different from procedures that you would write for yourself, except that the details of performing a task are invisible.
