IEEE and The Open Group Okay ‘Linux Manual Pages Project’ to Incorporate Material from the POSIX® Standard

PISCATAWAY, NJ AND SAN FRANCISCO, CA, 21 January 2004 – The IEEE and The Open Group have granted permission to the Linux Manual Pages Project to incorporate material from the joint IEEE 1003.1™ POSIX® standard and The Open Group Base Specifications Issue 6.

This step will allow developers using the Linux manual pages to gain a better understanding of how to write portable programs utilizing IEEE Std 1003.1, “Standard for Information Technology-- Portable Operating System Interface (POSIX)”. The POSIX standard, which also forms the core volumes of Version 3 of The Open Group’s Single UNIX® Specification, defines a set of fundamental services needed for the construction of portable application programs. IEEE and The Open Group have granted permissions for reuse of material in the Linux ‘man pages’ project (see: covering over 1400 interfaces from the standard including the headers, system interfaces and utilities.

“ We could not quote the POSIX standard verbatim until now because of copyright restrictions,” said Professor Andries Brouwer, who oversees the Linux Manual Pages Project and is based at the National Research Institute for Mathematics and Computer Science in the Netherlands. “As a result, inaccuracies crept into pages written by volunteers, because they had to interpret the standard in the text they wrote.

“ The approval we’ve received from the IEEE and The Open Group to reuse POSIX documentation in the Linux man pages will make the exact standard available to our volunteers. Needless to say, we’re very grateful to both organizations for the permission to do so.”

Andrew Josey, Director of Certification at The Open Group and Chair of the Austin Group, said: “We’re taking active steps to increase the adoption of POSIX within the software community. Making POSIX more available to Linux developers is one such step. Another was the recent decision to make the POSIX standard freely available on the Internet."

About the Linux Manual Pages Project

The "man pages" project provides the Linux system with manual pages so programmers have the documentation they need to write portable code. This documentation describes what the various standards say about a function or program and any special properties or deviations from the standards in the Linux libraries and kernels. This project was started by Rik Faith and has been maintained by Andries Brouwer for the last nine years. The “man pages” distribution can be found at the ftp site of the Technische Universiteit Eindhoven at

About The Open Group

The Open Group is a vendor-neutral and technology-neutral consortium, whose vision of Boundaryless Information Flow™ will enable access to integrated information within and between enterprises based on open standards and global interoperability. The Open Group works with customers, suppliers, consortia and other standard bodies. Its role is to capture, understand and address current and emerging requirements, establish policies and share best practices; to facilitate interoperability, develop consensus, and evolve and integrate specifications and open source technologies; to offer a comprehensive set of services to enhance the operational efficiency of consortia; and to operate the industry’s premier certification service, including UNIX certification.

About the IEEE Standards Association

The IEEE Standards Association, a globally recognized standards-setting body, develops consensus standards through an open process that brings diverse parts of an industry together. These standards set specifications and procedures to ensure that products and services are fit for their purpose and perform as intended. The IEEE-SA has a portfolio of more than 870 completed standards and more than 400 standards in development. Over 15,000 IEEE members worldwide belong to IEEE-SA and voluntarily participate in standards activities. For further information on IEEE-SA see:
