Preface

MPE/iX, Multiprogramming Executive with Integrated POSIX, is the latest in a series of forward-compatible operating systems for the HP 3000 line of computers.

In HP documentation and in talking with HP 3000 users, you will encounter references to MPE XL, the direct predecessor of MPE/iX. MPE/iX is a superset of MPE XL. All programs written for MPE XL will run without change under MPE/iX. You can continue to use MPE XL system documentation, although it may not refer to features added to the operating system to support POSIX (for example, hierarchical directories).

Finally, you may encounter references to MPE V, which is the operating system for HP 3000s not based on PA-RISC architecture. MPE V software can be run on the PA-RISC (Series 900) HP 3000s in what is known as compatibility mode.

The MPE/iX Developer's Kit Reference Manual, Volume 1 (36430-90001) describes the POSIX/iX library provided with the MPE/iX Developer's Kit (36430A) on 900 Series HP 3000 computer systems. This manual is intended for experienced C programmers.

This manual is organized as follows:

Chapter 1 Introduction provides a summary overview of the POSIX/iX library.
Chapter 2 Using the POSIX/iX Library provides information on general C library considerations and how to develop applications using the MPE/iX Shell and Utilities.
Chapter 3 POSIX/iX Library Implementation Considerations describe important MPE/iX implementation details you need to know when using POSIX/iX library functions.
Chapter 4 POSIX/iX Library Function Descriptions presents the syntax and descriptions of POSIX/iX library functions, arranged alphabetically.
Chapter 5 POSIX/iX Header Descriptions describes the contents of header files required by the POSIX/iX library.
