Getting System Information Programmer's Guide

Chapter 1  Introduction 

As you work with MPE/iX, you may need to retrieve various types of system
information.  Some questions that you may have are

   *   What are the characteristics of this file?

   *   What UDCs are in effect for this session?

   *   How many users are currently logged on to this system?

   *   Is this process executing properly?

   *   What is the time according to the system clock?

   *   What jobs are in the queue?

   *   What capabilities does this user have?

   *   Where is the console?

A variety of commands and intrinsics are available on MPE/iX to help you
answer these questions.  You can use many commands interactively, or you
can utilize commands and intrinsics as part of a programming task.

Each chapter of this manual covers the commands and intrinsics that you
can use to obtain a particular type of information; for example, file
characteristics or process data.  Within each chapter, system information
functions are grouped by task.  That is, if you wish to answer a specific
question or obtain a certain type of data, the system functions that you
should use for this purpose are described.  A table of tasks appears at
the beginning of each chapter.  It summarizes the types of information
that you can obtain and the commands or intrinsics that you can use to
obtain this information.

The usage of some commands and intrinsics overlaps.  For example, there
are several ways to retrieve time and date information on the system.
This manual describes the recommended method in these cases.

This manual introduces the commands and intrinsics that enable you to
obtain system information.  For detailed information and syntax
descriptions, consult the MPE/iX Intrinsics Reference Manual 
(32650-90028) and the MPE/iX Commands Reference Manual, Volumes 1 and 2 
(32650-90003 and 32650-90364).
