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:
* Accessing and altering files
* Requesting various utility functions
* Accessing system resources
* Manipulating and managing processes and system resources
* Returning values to a caller through the use of parameters or
functional returns
Intrinsics are no different from procedures that you would write for
yourself, except that the details of performing a task are invisible.
